Cologne Central Railway Station

I was in Cologne on holiday and needed the toilet at the main station (HBF) near the Cathedral in the centre of the city. The accessible loo was kept locked but by ringing a doorbell I could gain entry. (I use a mobility scooter). The loo was very clean and even had an adult sized changing table - I did not use this. It had everything you would expect of a full service accessible toilet. Top marks from me!
