How to see Trains in Mafia II

I found the train station in Mafia II and noted that there are some interesting variations on engines and cars, the steam engine i see in action in the Chapter 2 winter period i wondered if we can see that parked anywhere? I saw one short train go over a bridge in the mission where we have to fight thru a large factory, but havent seen any other trains in motion since then. I saw a promo pic of the main character in a convertible with a train in the background in an authentic Penn Central livery but all the trains i see in the game are wearing generic non realistic paint, i assume because of trademark restrictions. Any info on the steam engine and any other way to see moving trains? can we get into the train station we see in the opening video? that was cool. thanks for info on this. If i can work with the textures i can try to restore the correct livery on the trains that are there, but need to know how texture modding works in II. thanks
