there def won't be enough in a treasury (initially) to build any tracks/etc., so where does the start-up $$ come from? the rules state that things like building track must come from that RR's treasury (and not from a player, for example), but where exactly is all that $$ coming from?
($$ earned via the initial bidding won't be enough for sure)
If it isn't enough, the railroad will have to issue shares. The only way that money enters the treasury of a company is for a player to buy a share at auction. Maybe you should bid more so it will be enough.
