I've had the miserable pleasure of having to catch a train home twice this month. Both times the train was late by approx 40 mins. The cost of a 25 minute journey was 5.00 GBP! Monthly, i think it's 120.00 GBP! On the second journey, the solitary toilet was out of order. My local train station and the city station close to work is a miserable platform, again without a toilet.
Tactical solution - drive.
You have a toilet in your car?
