Thanks for bringing this to our attention.

I travel to Croydon almost every day and East Croydon is certainly easier for my purposes.

It is fairly easy to change at Norwood Junction for a train to East Croydon as the train is usually the other side of the platform.
And as said already, the tram is also quite easy as it's only 2 stops.

However, going the other way (East to West Croydon) is not great. The tram takes a round about route due to a one way system (minimum 10 minutes). The alternative changing at Norwood Junction will involve stairs. There are buses which depending on traffic can get to West Croydon in under 10 minutes. Also, I don't think West Croydon is totally step free either.
