Berlin Or Not Berlin , That is The Question

Terrible as the weather was I set off by train to Liverpool to visit the shops.Not a shopaholic by nature ,what I did know, there was a store with a pair of boots my size .( in Manchester zero ) A pleasant train journey to Lime Street Station and then onto the underground to the best stop for me.  Imagine my  astonishment on seeing the bright yellow train. It gave me a strange feeling someone had beamed me back to Berlin . However there were clues this wasn't so.Mainly the  lack of graffiti ( 3 cheers)The station was very clean.Once above the ground my eye caught the notice outside a pub.This I found amusing and oh so British . Whoopee still in UK .
