I will be changing platforms at Stevenage in a few weeks. Looks like we will arrive at platform 1 and need to get to platform 6. My companion is elderly and uses a wheeled walking frame. The general information that I can find is that all platforms are step free access but then see other information stating that there is lift access to platforms 1 - 5. No mention of platform 6. Just want to be absolutely sure that we will have step free access between the two platforms and also if anyone knows how reliable the lift is ( I have frequently seen lifts out of action at stations). On another note the information about access on most rail company websites is appalling. It would do so easy to provide a site plan so that a traveller can work out for themselves what it will be like navigating the station - what ever their access needs. Thanks.
