Dear readers,

I have a question about the train station procedure. When I'm at a small train station I see a pole with a ring on it. When the train arrives, the ring is ripped off the pole by someone from the train.

It is my understanding that because there is a single track track, this has something to do with safety. I can't figure out exactly what's going on. Who knows?

Sincerely,

Gerard

    I don't know, but I suppose that a train is not allowed to leave a station on a piece of single track railway if there is no ring at the station, because the train from the opposite direction has not yet arrived and the track so not free.
    Only the owner of the ring can therefore use the piece of single track and there can never be 2 trains on the same track.
    Of course, that only works if there are no more than 2 trains on that track.

    Ruud is right. I checked that once and that is indeed the explanation. There is such a ring per route and if it is not 'back', the next one is not allowed on that track.

    On a travel blog (so I didn't check the facts further) I found this:

    That is why there are always two people working at a station, the chief and his assistant. They operate the switches manually and handle the ring. That is a large iron ring to which a small bag is attached. When a train arrives, the assistant hangs that ring on a pole. Then he walks towards the train. The driver hangs the same iron ring from the window and the assistant takes it. The train continues and the driver takes the ring off the post to hand it in at the next station. There is a coin in the bag. The assistant walks into the building where all the levers for the switches are located. There is also a machine for the disc that is in such a bag. This disc must be inserted into the machine to verify that the train has arrived at this station.

    You can forget that when the high-speed train comes to Thailand. Not then???

    This is an old English system, but it works well.
    Only has a huge disadvantage, only 1 train can run on the single-track route at a time, so two trains in a row in the same direction is not possible.

      That is not a problem with the timetable in Thailand.
      There are not that many trains.

    It is indeed an English system, which is also still widely used in the UK on single-track sections - HS lines are double track.
    There is - because in this life there is a solution for everything - there is a procedure to allow 2 trains to go one after the other on such a track section - train 2 then only receives ring + coin - train 1 a kind of license for the next post. If the track section is at the end of a line, this is called: 1 train on tack system.

    The ring on stations has to do with the so-called system of “tokens”

    Operates on single track sections.
    When the token has been delivered to a station by the train, it can either be placed in the signaling installation to allow the track section to be released again, or it can be used in stations without real security as a “driving mandate” to the driver of a return train datum.

    It becomes a bit more difficult if several trains have to leave in the same direction in a row.
    The bag attached to the token contains a code or key that unlocks the track section.

    Issuing and handing in the tokens is part of the security of stations and track sections.
    Things like this are handled with the utmost care, also in Thailand

    I experienced a few years ago in Belgium when there was work on the coastal tram line.
    A kind of relay baton was then handed to the waiting oncoming train.
    Without that stick you were not allowed to drive on that piece of track.

    If you follow the TV series “Rail Away” it sometimes occurs.

    in modern European countries this is done by getting a lock. This is done by telephonic contact and by switching on something electro-mechanical.
