I managed to "tick off" catching a train to/from every central London terminus today, as I made it to Fenchurch Street, Moorgate and Waterloo East.
On the way into Waterloo earlier today I felt a tad disheartened seeing a 450 in the bay platform at Woking as I've only seen 455s in that platform for as long as I can remember. However later I was quite chuffed to see a 455 waiting to take me to Surbiton from Waterloo. I'll be honest, 455s were never trains I rode often, but the experience on board one of them today felt quite surreal, proper loud and clunky.
