I go for Portsmouth Harbour. It's a partially derelict dump, nicely matching the dump on the other side of Spithead - Ryde Pier station. I know the engineering challenges are rather bigger than for most stations, but Portsmouth as a city needs all the help it can get and a complete rebuild to create a seriously modern interchange there for trains, buses and ferries together with eliminating that bafflingly missing direct link into Gunwharf Quays, would give the whole city a lift.
No wonder the weather was odd, Mortimer is in Berkshire.
Next station down, Bramley, is a special case where, if you're on the wrong side approaching the station and the train is imminent, you'll miss it, because there's no footbridge and the only way across is via the level crossing whose gates have just closed.
It would be a blessing for the whole community (5000+), as well as passengers, to have a public footbridge built at Bramley station.
