Hi all, Just a couple of suggestions - not sure if they can be worked on or included at all. 1) Bridge strikes. I know that some sims have a major disruption (Edinburgh and Cambridge) element built in - could this be extended to including bridge strikes? In reality (as I'm sure most of you know), it is not always a case of immediately stopping trains after a strike. Some are graded as red, in which case it needs to be examined by a specially trained bridge examiner before trains can run. Some are amber or double amber, with initial restrictions of 5mph and then (IIRC) 20mph until an examiner gets there. This may be too much of a stretch with the data that would be required etc, though. 2) Rough rides. Drivers report rough rides every now and again over certain sections of line. Generally a 20mph caution etc., will be placed in the affected area until P-way attend and examine / fix the issue (or say no fault found). I'm not exactly sure how this may be inputted into a sim though - would this be easy to implement in the core code? What do people think? Cheers, Joe Last edited: 01/11/2018 at 17:16 by Joe S Reason: None given Log in to reply |

Can't say I've experienced one on Cambridge either.

Major disruption for Edinburgh was the airport tripwire activating and Cambridge had an option for single line working during engineering. Im not sure about the bridge strike option as it would require a lot of reverse engineering to add data for every over and under bridge, most of which aren't marked on the panel. The rough riding seems a reasonable option to add, of course the other one to add there would be a driver reporting poor adhesion. "We don't stop camborne wednesdays" Log in to reply |

I know Motherwell/Edinburgh/Paisley have a 'major failure/disruptive' event. On difficult setting Motherwell has OHLE down at either one of two locations. (Between Uddingston Jn and Coatbridge Jn Mainline & Law jn - Shieldmuir Mail terminal) Edinburgh has either Winchburgh Tunnel alarm or Airport trip wires or Wires down between Porotbello jn and Monktonhall Jn. Paisley has Glasgow Airport Trip wires or Prestwick Trip wires. Personally I would like to see a variation of location of OHLE wire problems/power trips. Your issue with bridge strikes is that, unless you have locations of every bridge, and then target the correct TCs to impose a ESR/TSR.

The rules around bridge strikes aren't simple either, light vehicle dispensation, BSE dispensation, and lots more come into it.

I personally don't see the point of either. Bridge strike aren't that common & regarding rough rides on track you've already got that in terms of TSRs, which is what would be put in place if one was reported.

Lots of good stuff about the difficulty in regard to setting up something which would encompass every bridge on every sim, but what is the OP trying to achieve? The way I read it, the OP would like some variants on the failures theme to spice up the game and add a bit more realism at the same time. If my reading is correct, then needing the data for every bridge in every sim is over-complicating what is wanted. The OP's end game could probably be achieved with just a few bridges in the sim identified and enabled for the bridge strike scenario. In regard to the marking of the bridges on the panel, what happens in real life. Presumably some sort of message arrives at the panel to tell the signaller that a bridge has been struck. How does the signaller identify which bridge it is and where it is located? Lots of obstacles identified in this thread to having an all-singing, all-dancing solution but is that what is actually needed? “In life, there is always someone out there, who won’t like you, for whatever reason, don’t let the insecurities in their lives affect yours.” – Rashida Rowe Log in to reply |

What is the mechanism in SimSig for a driver to report a rough ride so that a TSR can be implemented? “In life, there is always someone out there, who won’t like you, for whatever reason, don’t let the insecurities in their lives affect yours.” – Rashida Rowe Log in to reply |

A rough ride would not result in a TSR initially, an ESR (likely without the boards) at best, a job stopper at worst. postal in post 113049 said: Lots of good stuff about the difficulty in regard to setting up something which would encompass every bridge on every sim, but what is the OP trying to achieve?

Control ring you and advise you a bridge has been struck (Occasionally it's other rail staff, or members of the public direct), they give you the bridge number, you then look it up in the bridge strike appendix for your box and then take the appropriate action.

All bridges over the network be it road over rail, or rail over road have placards on either side with the bridge reference number, location & bridge indentificatopn number. The contact phone number would be the Network Rail control number responsible for the line of route control who in turn would advise the signalling centre responsible where the bridge strike has occured. The line(s) would be blocked to traffic until a bridge examiner had carried out a survey of the bridge structure. Once he has passed the bridge safe for traffic to pass over or under it then & only then would the lines be re-opened for traffic to pass.

In regard to bridge strikes, Network Rail has a page on its web-site covering the issue. The most recent data is for 2017/2018 when there were 1801 underline bridge strikes and 132 overline bridge strikes reported. The most frequently hit bridge was bridge BGK/1568: Stuntley Road (A142) in Ely, Cambridgeshire which was struck 32 times. So strikes are not common but some sites would certainly seem to justify their inclusion in the failure regime. After all, we have the tripwires for the airports in the McSims and how often are they activated in real life? “In life, there is always someone out there, who won’t like you, for whatever reason, don’t let the insecurities in their lives affect yours.” – Rashida Rowe Log in to reply |

I am not questioning NR documents, but according to Google Maps the road that the bridge is on is called rather fittingly Bridge Rd Log in to reply |

Coding it would essentially be a variation on the theme covered in the Sims referred to above. Also, Victoria LUL has randomised platform incidents based on the same idea. Peter I identify as half man half biscuit - crumbs! Log in to reply |

Once he has passed the bridge safe for traffic to pass over or under it then & only then would the lines be re-opened for traffic to pass. Not necessarily - as above, there are various dispensations to allow traffic to pass with or without restrictions whilst waiting for someone to inspect the bridge. The last one I dealt with, I found out about because the MOM just happened to be in the adjacent box (the bridge was in the section between the two of us) when Control rang his mobile to find out where he was and to ask if he'd mind popping to have a look. I don't suppose we'd have known anything about it until much later otherwise... It'd certainly be an interesting feature to consider, either way, maybe just for the relatively few bridges at which this is a regular event! I'm not sure how you'd caution drivers in Simsig though, either for a bridge that they can pass over/under with restrictions or following a report of a rough ride - since you have to pass specific information rather than just the generic "proceed with caution" or "examine the line" options?

Just ask him to examine the line, that is as good as a caution in SimSig.

Joe S in post 113042 said:Ahem. Cambridge *does* have a bridge strike. In fact, the bridge strike in Cambridge is the first major disruption element that any SimSig simulation ever had! It's not in the manual nor was it advertised. I did say once or twice that there was a "hidden feature X" (or some such words). I still remember the indignation on the forum the first time that someone ran into it. (Unfortunately the post seems to be too old to have been saved.) Log in to reply |

Seem to recall it only applied on the hard scenario setting which further limited the odds of finding it. I think your Edinburgh sim had something similar, a fault on the airport trip wire which closed lines and then left an epic TSR in its wake IIRC! There's the right way, the wrong way and the railway.

Apologies! :$ But yes, it certainly did - the nature of the failure put you as much in the seat of control as it did a signaller! There's the right way, the wrong way and the railway. Log in to reply |

I know it's the nature of the sims to be 100% accurate wherever possible and in scenarios from a signalling perspective etc., but just a bit of different variety would be good at times I feel.
