GOOD question! :)OK ... it's been over 40 years since I worked there now, but as best as I remember, the track circuit that you're ON has the tripper "behind" you retained (or down). This is why you have to bridge the insulated joint between the block you're in (moving forward of course) onto the advance track circuit in order to key by and drive down the stop in order to proceed. Therefore, the track circuit your train is occupying will have the tripper behind you down as well for each track circuit that you DO occupy. Could be wrong, but that's what I remember. |
