When with CSX you have SD40-2s, ES44DC, ES44AC, ES40DC (If you want to count that), C40-8s, C40-8Ws, SD50s, SD50-2s, SD50-3s, GP38-2s, GP39-2s, GP40-2s, Mother + Slug sets, SD60s, SD70macs, SD70ACes, SD60Ms, SD60Is, AC4400CWs, AC6000CWs, SD45-2s (Either the last 2 or the last one maybe in storage), GP15-1s, Gensets, MP15DCs, and even an SD40. *These are just off the top of my head, not accurate or fully studied*.
The point I am trying to get across: the eastern Class 1 railroads have alot more variety in power than the western railroads do. With CSX, you can have all these weird last-ups on road trains (Especially on inter-divisional road trains) and NS aswell (Depending where you are), but with BNSF and UP, it's either SD70Ms, GEVOs, Dash 9s, or SD70ACes, with the exception for yard and industrial switch jobs . I was out west this past summer and even the locals were using GEVOs and Dash 9s. Meh!
Unfortunatly, CP Rail is heading towards the same fate as BNSF and UP has. I mean look at all the SD40-2s that are dropping like flies on their system. I'm suprised that the Cowl units are still around (As far as I know of) and all the other SD40-2s have been sidelined from road trains for AC4400CWs, GEVOs, and the occasional SOO SD60 that can be seen.
Also, CN is a good railroad for variety of power (For now atleast), but that's mostly from the stuff they have acquired from god knows how many railroads they bought.
But it is all shrinking as far as the "good" power and includes the variety of paint schemes from railroads CN bought. Look at the EJE, as soon as CN took over, all of their SWs and SD-Ms were all gone and it's only a matter of time for the EJE SD38s and most of the IC SD40-2s for that matter.
