How does one set signals bang road in the bidi sections? DOFI's stay lit for normal direction when all controlled signals set to red and routes will not set wrong line into the section. Nothing in the manual covers this.

Once you have cancelled all of the routes set in the current direction of travel click on one of the opposing arrows and the direction will change. I will add a section to the manual later this morning. Last edited: 14/12/2018 at 07:08 by Andrew G Reason: None given Log in to reply The following user said thank you: Mattyq |

One thing that jumps out to me - there seem to be a few banner repeaters missing - MS4132, 3882 and 4110 (Wilsmlow 2, 3 and 4 in the down direction) all have banners at the beginning of the platform. Also MS386 (Cheadle Hulme, up Stoke) and MS4120 and 3894 (Up and Down Wilmslow, up direction) should have them. I do like the delay in signals stepping up - very accurate!

Set a route from Wilmslow DRS with 3S50 behind it - MS4109 changed to an odd white flashing square, which stopped flashing and solidified when the route was set and proved. When MS1715 returned to danger, MS4109 returned to a normal danger aspect as well.

Another one - ACI doesn't seem to be working at Alderley Edge or Macclesfield.

While keying the facing crossover Normal at the south end of Chelford loops prior to talking 6E64 over a track circuit failure I was surprised to find that the crossover isn't double-ended, instead being two single-ended sets of points. Out of curiosity I randomly tried a few other crossovers and found them also to be two single-ended set of points. Is this the case in real life? I also tried the Macclesfield crossovers but they are all double-ended, and I've also discovered in the Stockport sim that the Stockport 1 Fast-Fast crossover that is released by Edgeley 2 is also two single ended sets.

0K99 hasn't entered from Northwich East - its now an hour late. It isn't showing as entered, and has no rules prohibiting its entry.

Single ended crossovers are more forgiving in times of failure - if the other end is on another track but not detected, it may be possible to get clear signals on this track. Depends on facing Vs trailing. Conversely there is more locking and thus cost required for single ended crossovers. SimSig Boss Log in to reply |

Depends on facing Vs trailing.There is always a trade-off somewhere, in this case between installation cost and future flexibility in a failure situation. DY683 points at Stenson Jn near Derby were a 4-ended set which could be prone to giving problems so in the mid-90's they were fitted with split detection which I think was A&B, C and D. It meant that if one end on the Castle Donington branch lost detection we could still at least talk by on the main lines as long as the relevant ends had normal detection.

And partially it's just part of "that's how things have always been done" - as far as I'm aware, Germany for example has been using single-ended points almost exclusively since way back. Two million people attempt to use Birmingham's magnificent rail network every year, with just over a million of them managing to get further than Smethwick. Log in to reply |

Phil-jmw in post 114086 said:Jan in post 114080 said:I have a suspicion this has its roots way back when. As Phil says, single- ended points were the norm on the LNWR. Richard Foster, in his book on LNWR signalling, says it was a confirmed policy - it led to less stress on the rodding, made everything easier to set up and therefore was considered more economical (less work for the S&T). The Midland went to the other extreme of course, with 'economical' FPLs (FPL driven by the same lever as the ponts) very common; they considered it more economical because you needed less levers even though it meant a complex drive mechanism and sometimes difficulties setting everything up. Most of the UK companies went for the halfway house of working both ends of a crossover off the same lever, but separate FPLs. After the grouping that becme the norm for all 4 companies. Of course once point machines with built-in FPLs came in, habit dictated that the old practice of working both ends with one lever continued, and that way of setting things up continued into panel design.Phil-jmw in post 114047 said:In Germany maybe, but not so common in the UK, hence the surprise.GeoffM in post 114042 said:Single ended crossovers are more forgiving in times of failure - if the other end is on another track but not detected, it may be possible to get clear signals on this track. Depends on facing Vs trailing.There is always a trade-off somewhere, in this case between installation cost and future flexibility in a failure situation. Trapping arrangements could add considerable complexity of course, albeit mainly in the interlocking, especially where you had a double crossover between lines paired by use. Some of that used to be included in panel design, although I'm not sure whether it is still the norm in this age of TPWS and all the other anti-SPAD initiatives. Log in to reply |

Two questions re locations/ timetabling: 1) From memory, I think "Murgatroyds Siding" is what the location list refers to as "Sandbach Hays Chemicals" (actually part of BP)? If so, what key points need to be included to obtain a valid timetable path from Sandbach station to those sidings? 2) Middlewich British Salt does not appear to have a location specified in the locations list, nor is it a valid entry/exit point. Or am I missing something? EDIT - one other item noted. The line codes when timetabling heading south from Sandbach have FL/SL as options, though onscreen designations are Up/Down Wilmslow for the fast/ passenger lines and up/down Manchester Independent for the slow/ goods lines as per the Sectional Appendix. Deliberate to make timetabling easier? Last edited: 18/12/2018 at 14:56 by whatlep Reason: None given Log in to reply |

Further issue - trains entering from Northwich South Jn There seems to be something preventing trains entering from Northwich if a train has previously used the line from Sandbach northbound. Using the attached file, starting at 00:00 northbound trains work fine, but trains due to enter at Northwich never appear. With a start time of 02:40 the southbound train due at 02.41MX works fine.
