Mystery platform

Went to church this morning for baptisms, which was awesome :) had a costa lunch and then finished off The Big Bang Theory.
We had to leave to get the train a bit earlier than planned because of Sunday times, and when we got to Central James' train was from Platform 0. Platform what now? Platform 0?! I am sure that has never existed before! I ended up walking home after paying for a train ticket as it was a 40 minute wait. And I was cold.
Just started Big Bang season 2 :)
