Passenger Trains > Replacement Freight LocomotiveDate: 02/08/20 19:43 Replacement Freight Locomotive Author: bnsfrr805 Can anyone out there explain to me why when Amtrak has a problem (Mechanical or due to Wreck) and it needs a new locomotive to continue there trip, why do the keep that power unit until they get back to there home base. Example, this week AMTK 169 was power for 21, around Hope, Ark. it struck some debris on the track and they need a new power unit. They picked up UP 8125 from Little Rock or Texarkana not sure, and continued south. This train stopped in Ft Worth were I know they have spare locomotive besides what they use for the Heartland Flyer. Continued to San Antonio, where there also was 2 spare units. On the next day north bound Texas Eagle # 22 it had same consist as it did the day before (AMTK 169 (trailing) & UP 8125 (leading), next day I watched 22 get turned after unloading and still had same power. Why did the not swap out power, I have seen this on other trains also. Can anyone tell me why they did not turn UP loco in and pick up AMTK loco??
Steve White Carthage, TX Date: 02/08/20 20:34 Re: Replacement Freight Locomotive Author: SN711 From what I’ve heard it’s cheaper if they return the borrowed freight locomotive to the location they got it from. Probably also depends upon if the spare Amtrak locomotives were not going to be needed right away or not for something else and how much more time would be lost switching the locomotives out enroute.

Dennis Posted from iPhone Date: 02/08/20 22:11 Re: Replacement Freight Locomotive Author: The-late-EMD To add to that, they not only have to return the borrowed freight motor back to the same location they pick it up from but the unit must have the same amount of fuel when amtrak got it. U.p. use to demand amtrak top off the tank but a freight have 5000 galleon tanks and p42 tanks only hold 2200 gallions, so amtrak renegotiated that agreement. Also U.P. use to charge $12,000.00 a day for use of their motors but I think that's been renegotiated too.

Date: 02/09/20 11:25 Re: Replacement Freight Locomotive Author: The-late-EMD Freight motors top speed Is 70mph. Although some model GE A.C.'s tops out at 75mph. When we had a freight leader we was limited to 70mph. Amtrak tops out at 79mph so we would lose a little time on the advertise.

I think the speed limit is the same whether the unit is online, idling, or dead in consist. If anyone knows differently, I'd like to know. Back in the early 1990s when I was working as a power distributor at a major railroad, I do not recall Amtrak being required to return the unit to the spot where it was commandeered. We were happy just to get our unit back. Differences in fuel levels can add up to big bucks, though. so a lending railroad needs to be careful with that.

If > anyone knows differently, I'd like to know. Absolutely correct. Max speed of DC traction units is limited by the rotational speed of the armature,so as NOT to damage the commutator bars. AC traction motors don't care. > Back in the early 1990s when I was working as a > power distributor at a major railroad, I do not > recall Amtrak being required to return the unit to > the spot where it was commandeered.
