Amtrak Locomotives

Amtrak has rostered a fairly small array of locomotive models on its western long-haul trains, if we discount the mixed fleet acquired at its initial creation.  SDP40F’s, F40PH’s, B32-8’s, P40’s and P42’s account for nearly all of them. (NOTE the eastern corridor electrics and hybrids are out of scope for my purposes.)

By the time I started photographing trains the SDP40F’s were gone and the few P30CH’s were relegated to places I never went, but I have managed to capture examples of all the rest. All of these examples are from the west, mostly on the California Zephyr, the Southwest Chief, and a few on the Ski Train or the Winter Park Express.

Paint schemes have changed over time. See the top Amtrak page for more on that subject.

Photos are arranged more-or-less chronologically, but you can use the table of links below to jump directly to a specific unit.

EMD Cowl Units: the F40PH

The F40PH is basically a cowled version of the GP40-2, with an added Head-End Power (HEP) generator.  These 3000-HP units began arriving in the late 1970s, and served Amtrak well for over 20 years.  Arriving in three groups, they were numbered (by group) in the ranges 200 to 229, 230 to 328, and 329 to 400.  The first group had smaller 1,500-gallon fuel tanks; the latter two groups had the larger 1,800-gallon version.  Nearly all F40PHs have now been retired or sold to other operations, so there is no real numbering conflict with the higher series of P42s.

Amtk CZ 374 265  In March 1984, Amtrak F40PH locomotives Nos. 374 and 265 are leading the California Zephyr westbound near tunnel 1, above the Highway 72 bridge just west of Denver.  No. 374 is in the relatively-new Phase III paint scheme, whereas No. 265 is still in Phase II.
AMTK CZ 316-358   July 1986 has Nos. 358 and 316 on the point of train No. 6, a half-mile east of the photo above.
AMTK287_063095 No. 287 leads No. 6 on June 30, 1995 at Glenwood Springs, CO.  By now there often were AMD103s on the route, and the days of the F40s were numbered.


Nos. 388 and 298 are leased to Ansco to power the Ski Train for the 1997/1998 season. Here they’re grinding up through Plainview on January 2, 1998. A common arrangement for two seasons, it turned out that to have only two units on the long train– one running HEP as well as traction power– was to operate right on the margin of reliability. Eventually, the operation began using three F40’s.

Bottom: the prior week (December 28, 1997) the same power leads the train through Crescent siding.

Amtk334 Nos. 334, 332, and 40-(something) are being leased by Ansco to power the Ski Train in August 1999.  Here the trio is at Winter Park, CO, waiting while the train unloads passengers.  Afterwards, they will take the train to Tabernash to be turned, and bring it back for loading later in the day. By this time, very few F40PH’s were left in Amtrak service.
For more views of F40 locomotives continuing in service for other railroads, see here and here.

GE B32-8 Units

To my knowledge I only saw one of these, ever. They wore a unique paint scheme (dubbed the “Pepsi Can” by railfans).  I only caught the unit on analog video; here is a screen capture of No. 503.


Here No. 503 is the trailing unit on the westbound California Zephyr at Rocky. This scene was on January 4, 1997.

GE Genesis (AMD103) Units: the P40

The AMD 103, or “Genesis” series, of locomotives was rolled out in 1993 as the next generation of diesel road power for Amtrak.  The first group generated 4,000 HP, and are designated as type P40.  They are numbered in the range 800 to 843.  Most were gradually mothballed as the P42’s came online, but since circa 2013 some have been reactivated.

AMTK822 812 Two P40s, Nos. 822 and 812, head up No. 5 at East Portal, CO on November 25, 1994.  They wear the first Genesis paint scheme, where the stripes fade out toward the back of the unit.  This was supposed to be reminiscent of a ribbon flapping in the breeze.  The scheme did not long endure, probably because it was hard to maintain.  Both of these units were repainted circa 1999-2000 in the Phase IV scheme, a la No. 16 below.
(Incidentally, No. 822 is now painted in the Phase 3 Heritage Scheme– I saw it in Gallup in April 2018 but the photo isn’t worth posting.)
Amtk CZ 822 812 A going-away shot: the same train enters the portal, and we have a closer look at the back end of the two units.  This scheme was only applied to the P40 series.
AMTK805 No. 805 is captured on video at east Rocky on 1/04/1997.
AMTK816-PalisadeAmtk816_2018-02 No. 816 has been repainted into Phase 5 and resuscitated for regular service again.Top: Here I caught it on No. 6 entering Debeque Canyon in Colorado, just east of Palisade (4/28/2014)

Bottom: On No. 6 again, this time at East Portal. (2/18/2018)

AMTK 824 On May 31, 2019, No. 824 is running second (and facing rear) on train No. 6 just west of Range, Colorado.

GE Genesis (AMD103) Units: the P42

Beginning in 1996/97, GE released an updated version of the Genesis, the P42.  P42s are nearly identical to P40s on the outside (minus a rear hostler window), but have an additional 250 horsepower. They are numbered in the series 1 to 207.  After the advent of the P42s, the P40s appeared only rarely on western trains, although after 15 were rebuilt they began showing up with some regularity.

The P42’s came in two batches. The first group (numbers 1 through 120) was built in 1996 through early 1997; the second (121 through 207) in 2000-2001.  The second order came delivered in the Phase V scheme, which was applied over the next three years to the initial order.

An observation about the Phase V scheme: close inspection of the rear “wave” (the blue curve) reveals that there are variations from one unit to the next.  To my eye it appears that the paint shops must simply mask them by hand.

Up-close detail photos of P42 Nos. 75 and 201: click here.

Amtk44 A pair of P42s led by No. 44 (No. 62 is trailing) have train No. 5 at Grand Junction, 8/01/1998.  Notice that the Genesis Phase III stripes do not line up with the stripes on the baggage car (or any other cars).
AMTK44_080298 Here’s the opposite side of No. 44, as the train pulls out of the station. You can see the stripes well.  The angle of the photo doesn’t show the large number very well, just small numbers on the cab doors.
AMTK19-1998-12-26 P42 No. 19 is on No. 5 at Rocky Flats, CO on 12/26/1998.  It wears the second Genesis scheme– solid stripes all the way to the back doors. This simplified design is basically a modified Phase III look, adjusted to deal with the nose contours on Genesis units.  About two years later it received the Phase IV scheme, and towards the end of 2003 was put in Phase V colors.
AMTK16 P42 No. 16 has the eastbound CZ at Glenwood Springs on August 7, 2001. It’s in the Phase IV Intercity scheme, not as commonly seen in the West as the other schemes, even though it matched the current Superliner Phase IV look. This unit was repainted in Phase V in Spring 2003.


Top: Three P42s, including Nos. 129 and 145, lead train No. 5 at Clay (west of Denver) on 8/5/01.  They are in the initial Phase V paint scheme with the high sill stripes.  The third unit is still in the modified Genesis phase 3 scheme (without the dots).  This view was shot from aboard the train.

Bottom: No. 129 trails on train No. 5 past Utah Junction (Denver, North yard) on December 16, 2014. Now it wears a conventional phase 5 scheme.

Note: In 2011, No. 145 was designated as the Heritage Unit for the Phase 3 scheme and repainted.

AMTK10 P42 No. 10 is on the team track at Denver Union Station on New Years Day, 2004.  It’s seen from the lounge car of Train No. 5 as it departs the station.  No. 10 wears the revised Phase V scheme with the lowered skirt stripes.
Amtk155 P42 No. 155 is on the point of Amtrak No. 5 on New Years Day 2004 at Glenwood Springs.  She wears the original version of Phase V.  Note that the red sill stripe is slightly higher, with a blue pinstripe below, and dark gray below that.  There’s also a small Amtrak logo below the cab windows.
Amtk65 P42 No. 65 is the trailing unit on Amtrak No. 5 on New Years Day 2004 at Glenwood Springs.  She’s in the modified Phase V scheme.


Top: No. 25 sits in at Denver Union Station on 12/31/2006. Amtrak has been keeping a spare unit here to protect the California Zephyrs. At the time of the photo, Denver was buried under its second blizzard in a week. The Ski Train in the background had been annulled the previous two days due to conditions on the UP.

Bottom: Here’s No. 25 again, this time in warmer climes on the eastbound Southwest Chief at Gallup station, 9/24/2011.

Amtk75-GJ-010506_01 No. 75 is running second on the eastbound California Zephyr at Grand Junction, CO on 1/05/2006.  On this day the train was being run as a stub operation west of Denver, terminating at Grand Junction, and as such was run without sleepers, baggage car, or lounge.  This locomotive has obviously run into something– probably a grade crossing accident– giving her a nasty crease across the nose.  There is no builder’s placard on this side, probably lost during multiple repaintings (or wreck damage?).  More views here.



TOP: No. 201 is on the point, same train as No. 75 above.
She looks sharp in late Phase V, despite several dings in the paint that have rusted through.  Note the mismatched paint on the access panel below the engineer’s window.  More views of No. 201  here.

MIDDLE and BOTTOM: No. 201 leads train No. 5 westbound
through Byers Canyon on August 9, 2007.  The alignment of US 40 on the opposite side of the canyon allows for good viewing in most cases, except for the code lines which were still in place at this time.

AMTK 18 No. 18 trails on train No. 5 on 8/09/2007 in Byers Canyon, CO.  A decent overhead shot which shows an interesting weathering feature: since Amtrak usually runs elephant-style, the exhaust grime sweeps almost exclusively to the rear of the unit.
AMTK 59 No. 59 leads train No. 5, the westbound California Zephyr, on 12/6/2008.  Photo taken at the base of the Big 10 curves west of Denver.  This shot clearly shows the two different shades of blue that have been used on these units– the panel around the headlights has the grayer version.
AMTK 197 Side profile of No. 197 as it trails on train No. 5, the westbound California Zephyr, on 12/6/2008. The train is passing the east signals of Clay siding, about 20 rail miles west of Denver.
AMTK 186 No. 186 leads train No. 4, the eastbound Southwest Chief, at Albuquerque on 2/26/2009.  Typical Phase 5B unit.  The conductor was quite a character, sporting an Aussie-style hat and full white beard.
AMTK 88 No. 88 is the trailing unit on train No. 4, the eastbound Southwest Chief, seen at Albuquerque on 2/26/2009.  Typical Phase 5B unit.
AMTK 123 No. 123 with 113, in Seattle on 7/24/2009.  Picture is a little fuzzy– we were on a moving tour bus at the time. Not sure what train this is, but it includes a Pacific Parlour car, which probably makes it the Coast Starlight.
AMTK 191amtk191 No. 191.

Top: Here it is on the point of No. 4 at Albuquerque on 2/07/2010.  The power have just been fueled and are pulling forward to the passenger platform at the depot.

Bottom: Opposite side, on No. 5 at Fraser, Colorado (2/18/2018).

AMTK 85 No. 85, on train No. 4 at Albuquerque.  There’s not a lot of room for photos right here!  Standard Phase 5b scheme. (2/07/2010)
AMTK 86 No. 86 is on  the eastbound Southwest Chief at Perea (east of Gallup, NM) on 9/11/2010.  The hurtling train left me no time to get a better vantage point than this.
AMTK 137


Top: No. 137 on the eastbound Southwest Chief at Prewitt, NM, 2/21/2011.  The train is flying past at full speed (79 mph) making it difficult for my auto-focus to adjust.  I got lucky with this shot…

Bottom: No. 137 is trailing unit on No. 5, the California Zephyr, at Westwater, UT. In truth, my attention was more focused on the leader, Heritage unit No. 156…

AMTK 194 No. 194 is trailing unit on the eastbound Southwest Chief at Prewitt, NM, 2/21/2011.
AMTK 50 No. 50 on the eastbound Southwest Chief at Gallup station, 9/24/2011.
AMTK146_Ruby No. 146, seen from 300 feet above in Ruby Canyon, west of Grand Junction. The pilot is at the east end of the bridge over McDonald Creek. Trailing unit is No. 24.  (Train is No. 5, April 26, 2014)




Heritage Unit No. 156, three views at Westwater, Utah.  This unit completely deserves a full roll-by…in 2011, Amtrak decided to commemorate its 40th anniversary by repainting one locomotive after each of its historical paint schemes. No. 156 sports an adaptation of the first scheme used after Amtrak’s creation.  The heritage units are extremely popular among railfans, and this one is arguably the most popular of them.  It’s definitely my personal favorite, although the Phase 2 unit is a close second.

(Train: No. 5, 4/27/2014, 4:30 PM)

Bottom: Opposite side, at Fraser, Colorado on 2/18/2018. The 156 was assigned to the Winter Park Express for most of the 2018 season, much to my delight when we rode the train.

AMTK203-Palisade No. 203 on the point of No. 6 entering Debeque Canyon just east of Palisade, Colorado. Note that one of the center headlights is dark. (4/28/2014)
Amtk168 No. 168 heads train No. 5 past Utah Junction (Denver, North yard) on the gray morning of December 16, 2014.
AMTK198atGrants-2015 No. 198 leads the eastbound Chief at Grants on 8/29/2015. This was one of those moments when the gates come down just as you park the car, and here comes the train! Lucky I got any photos at all.
Amtk9 Engine Engine number 9… Leading No. 6 around the curve leading into the Moffat Tunnel on 2/18/2018.
Amtk52 No. 52, trailing unit on No. 5 at Fraser (2/18/2018).

Notice that by this time, strips of 4-inch yellow Scotchlite tape had begun showing up on door edges. Scanning through my photos they are inconsistently applied, but always on the edge(s) of any of the three side doors.  UPDATE: these are pinch-point warning labels.

Amtk42 No. 42, the Amtrak Veterans Salute unit, rolls past the Winter Park ski area and into Moffat Tunnel on 2/18/2018.
Amtk43 No. 43, leading No. 6 into Glenwood Springs on 9/01/2018.
Amtk12 No. 12, trailing unit on train 6 rolling through the yard at Glenwood Springs on 9/01/2018.
AMTK133 7/19/2019
No. 133.

Top: It leads westbound train 5 out of Glenwood Canyon on 9/01/2018. This was the best shot I could manage, unfortunately.  P40 No. 816 was the trailing unit that day.

Bottom: A better shot, on No. 4 cruising through the Continental Divide cut on the BNSF Transcon just west of Thoreau, NM. (7/19/2019)

Amtk74 No. 74 is on the point of train 6 in Debeque Canyon on 9/03/2018.  Colorado River is in the foreground.
Amtk13 No. 13 is the trailing unit on the above train. It’s approaching Tunnel Siding, where a BNSF local had stepped aside for the moment.
AMTK 163 On May 31, 2019, No. 163 is running second on train No. 5. Here it’s approaching tunnel 29 below Pinecliffe, Colorado.

Note the non-standard curve on the rear-end swoosh paint.

AMTK14 7/19/2019 No. 14 is running second on Train 4, the Southwest Chief, as it crests the Continental Divide in New Mexico. (7/19/2019)
AMTK176 No. 176 is running second, same place as No. 14 above but in the opposite season.  It’s New Years Morning, 2021.

(I have better photos of the leader, No. 197, above.)

AMTK27_2022 No. 27 was the westbound leader on the Winter Park Express on 2/20/2022.  Here it’s stopped at the ski resort unloading passengers. Note the snow cover on the coupler. They began using these covers since the power swapped ends for the return run, and it made it easier not to chip ice out of the coupler when reconnecting to the train.
AMTK171_2022 No. 171 was the trailing unit on the Winter Park Express on 2/20/2022. On the return trip it would become the leader.

 EMD F59PHI Diesels

These locomotives were purpose-built for commuter railroads. 15 are in dedicated service on the Surfliner trains.  I managed to bag a couple of them during a trip to San Diego.

AMTK 450  No. 450 is leading a Surfliner train flying through through Rose Canyon in north San Diego. If you walk in this area, be aware these trains approach fast and quietly. Note it’s on the far track.
AMTK 453 No. 453 in nearly the same spot as the photo above, except that it’s pushing backwards up the valley. Note it’s on the near track.

Given the history of Amtrak’s painting practices, we can no doubt expect new paint schemes to appear as time goes on, if budgets allow.  The locomotive fleet is scheduled to undergo a major changeover to the ALC-42 Charger units scheduled for delivery later in 2021, but we shall see; they’ve been quite delayed already.  A new livery is planned for them, visible at the end of this video.  You can be sure we’ll be watching for whatever might transpire.
