The rules should be:
A company which has no train and has to buy one can choose any available
train of the bank or offered by other companies no matter how much money it
has. If the company has not enough money for the purchase of the chosen
train the director may add the difference.

My mistake. It's not the CHEAPEST train but ANY train available in the bank
(or offered by other companies).
