OR5.1
SPX is operating for the first time, and gets to the train buying step. There is a 3T in the discard and it is being offered to buy it. The rules are:
"A company that owns more trains than currently allowed must discard excess trains. Any trains that are discarded are removed from the game."
The company cannot buy the 6T because there is a cheaper train available i.e. the 3T - this is correct (if the 3T was really available).

This will presumably also affect other maps.
