There is only 1 set of ticket validators to access the Eurostar.

Can you please make sure that the platform multipolygon relations aren't broken when you are fixing the platforms like this relation/8108183
?

Sorry, they represented two steps, one over the other.

I have fixed it and added level tags now.

Sorry what did you do to the steps? The map is wrong now and I have to fix it.

Why do you keep removing the platform_edge all around the country? I surveyed these platforms and these platform edges are needed to correctly map the extent the whole length of the train, as part of the platform is fenced and trains do not stop.

I have seen that you have added some naptan:AtcoCode tags into the stop position on the tramway. This is wrong, and it should be placed on the platform instead.

In addition, the code themselves are wrong as well. The TfL timetable data shows that the platforms for the two directions have their own codes with 1 and 2 as their suffix.

I fixed the problem yesterday.

Please make sure that the platforms at different layers aren't joined together.

You have to add access=no for emergency paths, otherwise the router will attempt to use it to get to the platform.

I also did the same to some other stations, such as Tottenham Court Road, a while ago.

Those I left separate are those where there is a clear boundary on the ground between areas of responsibility, where the parts can be operated separately, like Liverpool Street.

It was intended. West Ham (the rail station) is now clearly one station (the entrance and concourse are shared so no part of the station can work independently without using that entrance and concourse) so there should be only one stop area for that station, and the name is just "West Ham".

The meaning of the ref= is the official route code. The codes I have put in are used officially in the TfL Go application and website to represent line status.

This is also the same in Hong Kong MTR network as well, where the 3-letter code is put in the ref.

Each of the 11 Underground lines is represented by one route master, therefore for consistency each of the 6 Overground lines need to be represented by one route master as well.
