General description : Fenchurch Street is near to the Tower Hill underground station and the Tower of London. Tower Hill is not accessibility friendly, actually I have discovered that there is a lift. Tower gateway is about 10 minutes from Fenchurch Street - this is an very accessible station on the DLR. See wiki
The accessible entrance served by lifts to the upper concourses, is only the Fenchurch street exit / entrance. There are also escalators for those who find climbing stairs a difficulty.

More comment : There are many fast trains which run from Fenchurch Street, via West ham and Barking. It is important to check the notice boards carefully for travel past Barking, as there are numerous routes. The C2C line is overland, and initially runs alongside the District line, but is considerably faster as it only stops at major stations. The steps and gaps onto the trains appear to be quite large on this route, and would be worth checking with the operators before using these trains. They appear to use ramps at Fenchurch street, seen May 2019, for example.
