I'm playing the central scotland sim, using the August 2006 timetable with Interlocking enabled. I've got a slow train that I'm wanting to route out of the way of a passenger service by sending into the Larbert North UGL - but I can't work out how to avoid a clearing point violation when I do. There's nothing ahead of the train, but as soon as it goes onto the goods line, and exits the main-line track section immediately before LN46 and the points I always get a violation. How is this avoided? The maps in the manual either aren't helpful - or, more likely, I'm not reading them right. Thanks in advance. Dave

My guess is (without reading the manual or looking at the sim) that you're getting it because the points at the end of the sidings are set reverse. You will probably need to set them to normal before signalling a train into the loop.

I don't know this to be true of Larbert North (note the spelling) but certainly my experience of Western boxes leads me to suspect that 37 would probably require 32 (the right hand disc (LN30 is the left hand disc, the two together are identified by the sim as LN30)) with 31 points reverse. But that would be enforced by the mechanical interlocking and isn't really a question of clearing points. Surely LN31 points are not in the clearing point with a colour light distant.

thanks for the note about the spelling! I do seem to have 'Lambert' stuck in my head everytime I think about this, even when I'm looking right at the sim. No, it's not the points ahead at the end of the loop - it doesn't make any difference how they're set - I still get a 'clearing point violation' as soon as the train clears the track section immediately before entering the goods line. It _feels_ like the the sim notices the change in occupation of the track section there, looks at the how the points at the end of it are set and goes 'Oh - that's wrong!' - ie checking the state of the points when the train is both entering and leaving the section instead of just when entering.

Looking at the diagram - and given that the train is being signalled into a goods loop (presumably the left hand arm on the bracket to enter the loop would be a short or miniature arm) I cannot see any possible reason for a clearing point violation. It was normal on goods lines for the clearing point to be the home signal; in this situation, for a goods train accepted from the rear section the clearing point is - correctly - along the length of the loop. Unless - but this would seem rather strange to my way of thinking - the train has to be accepted with the points set for the main line and brought to a stand at the bracket before the points are reversed and the signal cleared to enter the loop. Might be worth checking that. But I can't think of anywhere in my experience where that would have been the case. Log in to reply |
