In the lastest King's Cross V2.201 using the latest system files, after setting a route from signal 454 to 448 (between Bounds Green Depot and Alexandra Palace), I am unable to set any routes to signal 454. Trying to set a route from signal 476 or signal 474 to signal 454 both fail with the following error message: "Point(s) locked reverse by another route" Is my assumption correct that this is a bug?

It's because the routes 476/474 to 454 both require the overlap beyond 454 to be on the SL. To send a train 454 to 458, you need to set route to 454 only, wait for the train to stop at 454 and after about a minute the white overlap will 'drop-out'. You will then be able to set the route 454-448. It's a safety feature, it would be unsafe for a train to overshoot 454 with the points set to the goods line. There is a similar instance at the northern end of Hitchin Up Yard, signal 944. Hope that helps, also see http://www.SimSig.co.uk/dokuwiki/doku.php?id=usertrack:glossary:overlap and associated links I can only help one person a day. Today's not your day. Tomorrow doesn't look too good either. Log in to reply |

Thanks for your reply. I am happy to see that the behavior I reported was intended and not a bug. However, I don't understand why the UK signalling system uses the concept of delayed yellow. Wouldn't it be more meaningful to simply impose a stricter speed limit well in advance, to reduce the danger of a critical SPAD? Log in to reply |

That would go down well on an already overloaded section of line, putting a permanent 15-20mph restriction on a section with a line speed of 75-90mph to protect a crossover used maybe only a couple of times a day. And do you likewise protect every crossover the same way the length and breadth of the UK?

Here in Germany, the speed limit can be set dynamically, so that the signal displays a speed limit depending on the route that is set for the train. Log in to reply |

Our signalling is route-based not speed-based, so the signal indicates the route to be taken & the speed limits are set for the line (different speeds for main line & turnout). Of course neither system gives sufficient information so a degree of speed information is overlaid on our route system (flashing yellows at high speed turnouts & delayed yellows at low speed ones) while some route information is overlaid on your speed signals (indications of crossing to opposite line etc).
