Despite everything that has been said, I still strongly dispute that there are
4 trains per hour from Waterloo to Wandsworth Town in the evening peak period.

There aren't four - there are six per hour!

17.02 18.02 (Kingston via Richmond)
17.17 18.17 (Shepperton via Richmond)
17.24 18.24 (Weybridge via Hounslow loop)
17.33 18.34 (Kingston via Richmond)
17.47 18.47 (Shepperton via Richmond)
17.54 18.54 (Weybridge via Hounslow loop)

Are you sure you aren't limiting yourself to just one of these three
routes between Waterloo and Wandsworth Town?
