Public Transport
We talking about the train?
So I don't have enough to do in real life already but now I get to have fun synchronizing real life time to in-game time.
I would suggest something like taxis or a bus that is armed and guarded. Its a tad bit faster than walking but its safe and doesn't require time keeping. It would always be available at a city depot and all ya need to do is click the taxi and money is auto deducted from your caps. This way you can keep your cap sin your hand without the fucking thieves robbing you blind.
