Here are 170-179 road numbers in the 2000/2001 Amtrak Genesis order from the GE Transportation Division at Erie, Pennsylvania. All were originally delivered in the low skirt millenium (3G) paint as a part of the road number 169-207 group at Amtrak. Up until January 29, 2024, this was the only livery this group of 10 had ever worn. But #174 has now been restyled into a circa-2021 "midnight blue" (4G) paint scheme first pioneered on Siemens "Chargers" in 2014-2016.

Builder stickers also in the high position (but moved back to standard in subsequent overhauls). Steel noses were changed to the bolt-on variety over the intervening years. Three of the ten in the 170's group are out of service as of the start of 2024. The newly restlyed #174 does not have a builder sticker on the fireman's side, somewhat typical of what has happened in recent years. Originally the P42's had them on both sides.

Build dates for #170-179 are May and June of 2001. Serial numbers were originally out of order for #177, which has a May build date but a June road number assignment. Evidently it was bypassed in the assembly process for a week or two before being assigned its road number.

The looks of these units had not changed much in 24 years. All but #174 wear their original 3G platinum mist/bluenose millenium. As of January 29, 2024, #174 was the first to be restyled in a new 4G 2024 livery (the second so far in 2024 is #82). The most obvious previous change was the addition of the bolt-on nose cone, otherwise their original styling has just been refreshed from time to time. A forest of antennas have sprouted on the roofs with the advent of positive train control, with many other less obvious changes due to technology additions.

Some are dirtier than others, and the active ones are getting pretty far away from their last refresh dates, so it remains to be seen what will happen with them in the future. Of the original 38 low band millenium units, 28 remained in service at the start of 2024. The new 2024 paint scheme is reportedly slated for any of these that are still usable at their next major shopping. While the "navy" blue base coat evidently comes from Siemens 2014 series Chargers, the 2024 treatment is significantly different than the first groups of Chargers, and evidently represents Amtraks overall new marketing scheme.

Engine #174 is somewhat similar in appearance to 50 year anniversary engine #108, except for a second shade of blue on the flanks, and a white dividing stripe amidships. It will be interesting to see if any or all future locomotive repaints will be in the same vein as #174 was.

Some archived info has been moved to individual unit pages. Click on the serial number on each photo to see it. Here is the latest for the active units in group #170-179. It usually takes 48 hours or longer for us to get the reports. To track a particular train's history, you can go to Dixieland Software and the website. GPS plots of trains showing times and locations are archived at Not all movements are necessarily captured here and there can be errors in the reports we do have. The train assignment date(s) are here, except for the east coast, where only the date the diesel was in consist is shown. Typically the 170's do not run on the north end of the northeast corridor, so when you see an east coast assignment, it is usually out of Ivy City on the south end. The 500 series train numbers you may see see from time to time are Cascades in the Pacific Northwest.

There are seven actives in this group in April 2024. Two of the seven have some of the freshest paint in the fleet. Engine 174 went to Beech Grove for maintenance on October 29, 2023 and came out in revised paint on January 29, 2024...the first P42 in the new 4G style. It also did a special inspection train move Denver to Longmont before shifting to the ski train. It was picked up in Denver on April 3 by Train 5Apr2/4. Five locomotives, 13 cars, #23, #30, #174, #161,#7. One of the most impressive consists so far in 2024!

As of April 12, 2024, #170 and #175 were on different Chief sets, with #171 and #172 on different Silver trains, #174 is running Zephyr turns. Our last report of #176 was in Chicago a month ago, and #179 filling in on the Auto train or Piedmont in mid March. There have been no reports on either of them recently.
