Well for me things are rather interesting, I might be sometimes be met by staff due to my need of assitance for boarding, but quite often they will plunge the extra wide barrier for me at Cambridge, when leaving possibly as I know the Managment Team at NX EA and sometimes they don't bother asking to check mine, possibly as they know me but quite often I show it anyway but what's intersting is for people with assitance, sometimes at Stevenage they will ask to check tickets after the lifts, but sometimes on the way down they don't bother.
Also, what annoys me and puzzles me the most is at Stevenage, the accessible toilet is well on the wrong side of the barrier, when I think I pointed this out to FCC, I think there might have been a small feeling of embrassment by this, but anyway what is intersting is Bishops Stortford do not have any barriers at all, and may not do so, due to the station design but they might be possible but could cause a lot of problems.
Also, one station has had it's ticket machine stolen, this has lead in the long run I believe the ticket office being manned but most of the day it's an unmanned station. What interests me though is it could be possible at Whittlesford Parkway to catch a London bound train say to Bishops Stortford without a ticket and I've already told Managment about this but I do know in my personal circumstanse, I believe I have clearence to get a ticket at the other end for both directions of travel but I need to check this from this station but I do normally try and buy these tickets in advance, although I know I might be put to the front of a queue, if the ticket machines were non working at Cambridge but it is handy when you know people, at train companies as you can get much higher quality service than usual plus some of the best service I have ever experinced has actually been with NX EA and they've actually in the end worked with FCC when there has been a serious assitance problem, both have worked together for me to ensure problems I've had never happen again.
Although, I think Harlow Town has staff checking tickets, and this has caused problems getting to the accessible toilet once before, but it's been quickly cleared up, but to my knowledge, I've only had one ticket check in 4-5 trips but this may be down to more ticket barriers this just does make you wonder how many tickets do really get checked.
