I have been using the WAGR S Class diesel to level up at a cost of 8,895,000 coin it yealds 225,000 XP and has a good sell on value. Can anybody tell me what is the best thing to buy, and I mean anything not just trains, using just coin - up to and including level 228 to yeald the most XP? Can the WAGR S be beaten? Thanks :)
