>>1979649I cycled round there once a very long time ago (maybe 2011) just to see what was there and the main thing I noticed was that Hornchurch is a major town. Had no idea because it's just a single stop on the tube map and you never really hear about it compared to Romford. There's fuck all in Upminster despite the the large interchange station.
Emerson Park is near Hornchurch so that's probably the reason for that station. I suppose it continues to Upminster despite there being nothing there so that it can link the LTS with the GEML
