according to youtube cab rides there is a link from the line into platform 1 at Barking to LUL that's not shown on the sim. any idea why this was not installed? Log in to reply |

I was responsible for adding this feature (basically a Ground Switch Panel) into the TRESIM in around 2009 IIRC. As I understand it, this version of Fenchurch Street was a very early SimSig and was mostly a straight conversion to allow it to work on Modern versions of the software. The original sim would have pre-dated the link line connection by a very long way. There have been other changes since then such as altered signal spacing in the East Ham area, prior to the Olympics. Incidentally in all the times I have taken a train into Barking I have never managed to spot the actual connection, despite my best efforts!

" said:I was responsible for adding this feature (basically a Ground Switch Panel) into the TRESIM in around 2009 IIRC. Sorry Tom, it's West Ham where the signal spacing was altered. The link is absolutely right at the London end of Platform 1, only used (I believe) when the lines are under Engineers' Possession and looking pretty rusty and nondescript just at the moment (I have an idea it was installed to facilitate the massive track relaying programme that was undertaken between Bow Road and Upminster a year or two back).

Firstly, it wasn't there when the sim was first written (and the modern release deliberately hasn't been updated or had errors fixed). Secondly, when the sim was written the core code didn't have ground frames available, making it much harder to add it. Oh, three reasons: the sim doesn't have LU in it.

Secondly, when the sim was written the core code didn't have ground frames available, making it much harder to add it. Maybe a fourth as well: not just a ground frame and LU, but I'm sure this will have some form of co-operative release and bolt lock. Which is most definitely going to be 'fun' (if you're a masochist, that is). As was the release for the connection that used to be there to the LU line at Kensington South Main. Not only was the GF locked by Annetts Key released by the South Main release lever (even though the box was only 50-odd yards away); there was a release from the LT Regulating Room at Earls Court. I no longer recall whether their release was direct on the GF release lever or in the Annetts Key circuit. I do recall that the two releases had to be operated strictly in the right order for the points to be operated (and the withdrawing of the bolt lock was clearly audible, as it used a standard LT pneumatic points actuator). What was worse was that the correct sequence had to be followed to get the whole thing back, with the additional complication that, if detection wasn't obtained when the bolt lock was restored, you could lock up both lines completely immovably until both sides' S&T had been down and sorted the mess out...
