European Railroad Discussion > A Russian loco question?Date: 03/07/15 09:28 A Russian loco question? Author: NGotwalt I have long noticed that Russian motive power has two numbers assigned to it.
Take for example ЧС2К-523 (ChS2K-523) seen here: http://railinform.net/details.php?image_id=948 What North Americans would think of as a road number for this unit is ЧС2К-523, but beneat the cab is also 11005238, now I have determined that all ЧС2К's numbers start with 1100 (as do ЧС2s, which makes sense since the "K's" are rebuilt ЧС2s), even the completely different ЧС2Т, are assigned 1102. Now the next three numbers are the unit number, though this does not hold true for all RZD locomotives, the last number changes and can be just about anything...I cannot figure out if it has any meaning or not? Any ideas? Cheers, Nick Edited 1 time(s). Last edit at 03/07/15 09:31 by NGotwalt. Date: 03/07/15 12:29 Re: A Russian loco question? Author: Steinzeit Circa 1984, "all" Soviet loco, including active steam, and multiple unit classes were given all-numeric computer numbers, with the first four digits being the class. Steam started at 1000 [ with the P36 class ] while electrics started at 1100; electric MU's, 13xx and 14xx; diesel locos were in the 15xx and 16xx; diesel MU's, 17xx. I imagine the last digit is the check digit, just like most of Europe's rolling stock.
Hope that helps. Best, SZ Date: 03/07/15 14:13 Re: A Russian loco question? Author: NGotwalt What is a check digit? Is this similar to what Southern (US not UK) did with the letter at the end of the unit number?
Cheers, Nick Date: 03/07/15 14:53 Re: A Russian loco question? Author: Steinzeit Yes, same idea, just using the computed number instead of a letter substitute.
Your original post reminded me that SNCF gave its active steam locomotive fleet two digit computer number "classes" in the late 1960's, and these were sometimes stenciled on the cab side underneath the cast number plate. Thus, 141R 412 also became 46 412 if coal fired, or 97 412 if oil fired. Best, SZ |
