As UP it had shortage of power, they requested help to CSX! Note: the freight cars are also of specific rail cars companies.
See ... a foreign transport company in a new locomotive, running down the hill with one car, no power. Apparently they are training before the winter bobsleigh rides on the Sand Patch Grade! hehe Best wishes ! / sorry if this joke offends you /
Achievements also counts for UP AC4400CW if CSX version was played heavily so its the Red DB BR442 Schnellfahrstrecke Köln-Aachen with Dresden-Riesa Achievement counting towards it.
Running a Poland locomotive on SPG?!... That is more than foreign power!...Jajaja I have several PKP locomotives and cars - both passenger and freight ones - on OR. I really like the paint scheme, and the design of the cars. But I run then on Wupper Express route. Best wishes for your too!
Well... in my case as I do not purchase Cane Creek, I do not have AC4400CW in UP colors. But it is better "impression".. to have foreign power as it happens on real world! Very common on US freight trains, also using Ferromex, CP and CN locomotives. Those are really "foreign" power!
