While looking through the photos of LAL20 and "Traveler" from yesterday,
I noticed #20 has a "ARS-10" class designation on the cab:
http://www.protocol7.org/gallery2/v/LAL ... ewsIndex=1
ARS must mean "Alco Road Switcher"..and the 10 means 1,000 horsepower.
Looking through photos, none of the LAL Centuries have a class designation like that..it looks like only LAL 20 and 72 (the S2) have it.
72 has "AS-10" - Alco Switcher, 1,000HP.

Did the LAL start using this system "way back when" and then drop it for some reason?
looks like its the same system the LV and the PRR used.
here are the PRR classes:
http://prr.railfan.net/diagrams/PRRdiag ... &sz=sm&fr=
A C425 in this system would be a "AF-25".
I believe for "Alco Freight - 2500HP"
the LV also used this system..perhaps slightly modified from the PRR.
I never much cared for it...why not just call it what it is!
like "GP38-2" rather than "ESM-20"!
I suppose it was probably developed by the PRR so locomotive horsepower could be determined at a glance..
so it was probably usefull at the time.
and the LV adopted it because they were controlled by the PRR.
I have never seen it in use other than on the PRR and LV.
most railroads just put the actual loco type.. (if they use anything at all)
like RS1, C424, U23B, etc..
