They should get a license from California to permit gaming as soon as the train leaves the station. If the LOLs can start dropping coins into the slots as soon as the wheels start rolling, they’ll fight each other to get aboard.
They could probably make more money on the slots than they do on the tickets!
On the old red eye bus trips my grandmother used to make to Vegas they started playing cards the minute the bus left. Probably wasn’t legal, but when you lock 50 gamblers together for a prolonged period good luck stopping them from gambling.
