I have a Phil and Ted and have used it on both the flat entrance trams (the new ones) and the older ones with the steps. I have only taken it on the older trams when I have someone with me to help me get it up the stairs. It fits in the doors ok. It is fine getting the pram onto the flat entrance prams by myself - when I am on my own I always wait for a flat tram as I just never know if someone will stop to help me.
