UPY Green Goat Genset Hybrid Reporting Marks

[Paul M.]

Most Union Pacific locomotives are lettered UP. The new genset Green Goats have UPY reporting marks. Other switchers have UP reporting marks, but this friday I saw what appeared externally to be a MP15DC switcher; it also had UPY reporting marks.

Anyone know why the gensets have UPY lettering? How 'bout the MP15DC?

It could be for UP yard service.

UP has 8,368 locomotives in service as of 2007 (source: AAR). UP created the UPY reporting mark to make it easier in numbering locomotives (i.e. MP15's, 1200 series; GP40-2's, 8300 series, and so on).

I think that they are running out of four-digit numbers--and rather than go to five like NdeM, they created the "Yard" series of numbers.  Probably more of the switchers will be getting these numbera sa they are shopped to vacate the road numbers.    Wouldn't you like to have "too many locos"?gj

Ok, thanks everyone. I think I understand now.

The MP15DC was #1345, if I remember correctly.

UP has at least 16 reporting marks I am aware of, I have the list if you want it.

The "Y" is for yard and short line. Railpower introduced the Green Goat, using much smaller engines and more batteries.  The concept and goal was to reduce fuel consumption by up to 80%, primarily while idling or putting around the yards. 

Another benefit was better visibility and automation.

Bob, I knew they had several reporting marks, but not that many.  Please post the list.

Things could get confusing UPY #1325 and UP #1325, both locomotives on the same railroad, both the same colors.   Hopefully dispatchers wiill not make a mistake and send the wrong orders to the wrong crew, or throw the wrong switch leading to an accident!!!

Rather than list them all, here are some links:

http://en.wikipedia.org/wiki/Union_Pacific

Plus 26% of Ferromex....total track owned/controlled...54,116 miles.

I have a copy of the master .PDF showing all the cities served.  It is about 275kb, would be glad to send it to you.

Locomotives were renumbered in the years 1997-2000+...no duplicate numbers that I could find.

Bob Just realized I forgot to thank you for the links!!

Great stuff. Thanks

You're welcome Bill.  Can you imagine how much research it took to make that site? And that's just UP, Don Strack also has all-time rosters for Rio Grande, WP and SP.

For UP's tracks, that's enough single rail to go around the world 4 times!

Some say UP, because they may not just be used for yard work, but some are chained to it with the Union Pacific Yard Locomotive symbol on it, if I ever work for them, I will just take a SD70M. By the way, a SD70M for UP had the roadnumber: 4669. Is that number different if it's a diesel, for if it was a steamer, wouldn't it be a big boy?

No, the Big Boys were 4001-4025 ('scuse the typo)
