Carriage doors inward opening

Hi All.   I have been watching a YouTube video on the Caterham Line ( from Dunton Green). A Push Pull Service with two converted carriages and an H Class Loco . There is a mixture of stock forming the trains, and the “ voice over”says that some of the doors open inwards , and it is very confusing . Personally I think it was a crazy idea , how would any staff know if the doors were open or closed? Especially the Guard. A recipe for accidents???
Best wishes. Kevin

Push-pull trains of old tended to be short (usually one or two coaches), so not that difficult for the guard to monitor. Pullmans also traditionally had inward opening doors, right up to the Mark 2 sets used for the Manchester Pullman train, but Pullmans also traditionally had attendants for each coach, so once again, not that difficult to monitor the doors.

At least if the doors were left open, they couldn't hit anything on the lineside or adjacent tracks. Many Australian long-distance trains had inward opening doors even up to recent times. Suburban electric trains on the major cities' systems (I'm thinking Melbourne and Sydney here) had hand-operated sliding doors that could be left open right up to the late 1980s - on Melbourne's older wooden Tait trains (last in service 1984), the flexing of the carriage bodywork when in motion tended to make the doors slide open of their own accord while travelling! There is a small danger of someone being thrown out, but it is still possible for people to do stupid things even with the most modern equipment on our railways.

Hi Jeff.  Thank you. Having travelled on the “re invented? VSOE “ to Venice , Prague and Budapest , I should have remembered that , but they did have attendants, which I thought were just a novelty. Thinking about it I remember hearing about “ Tank Stock “ on the District Line ( F)? With hand worked sliding passenger operated doors.     Best wishes. Kevin

Hi Jeff.   This is a second reply, I have just been watching another YouTube video, this time the same enthusiast had been filming on the “ Hoo branch” that really is a prototype for oddities, including a token station without a passing loop and just one member of staff who works the crossing gates as well.  Best wishes.
