Hello all, Does anyone know what this 'speed classes' list is about in the newer sims? It lists stuff like MGR, Wessex 442, Class 67 etc but what is it for and is it in use? Simon seems to think it's for the different speed classes that can be found on the network (like Sprinter 60 over 50 speed sections) which would make sense but some of them don't make sense to me. What would MGR be used in as I don't think there is such a speed section for MGRs only is there? The Class 67 LHCS, Class 373, Metro and Tripcock have got me baffled to, would anyone please explain to me what they are for so I know for future reference should I need it :) Thank you! James.

ive seen a MGR speed restriction sign before (referring to HAA rakes not current hoppers) . also 373s are limited to 110 max on not HS lines (ie not the channel tunnel) and were i beleive subject to some others while running on the ECML. tripcock relates to stock fitted/not fitted with tripcocks when operating on LUL lines (wembley suburban uses this catergory) "We don't stop camborne wednesdays" Log in to reply |

It's there so the developer can set different speeds for different types of train over and above (or below) the standard passenger/freight speeds. EG HST is one used a lot through Scotland on the ECML. The labels actually don't mean anything on their own it depends on what we make them mean i.e for HST speeds I could use MGR label but the end result would be the same. None are use in the GW 3 released, as and when they are the manual should say. Peter I identify as half man half biscuit - crumbs! Log in to reply |

They have been used on Oxted for a couple of weak bridges, the codes that you need to use have been put in the manual. Paul You have to get a red before you can get any other colour Log in to reply |

Okay, let me explain. On the real railway you get special differential speed limits. You can see examples of the signs used at http://www.railsigns.co.uk/sect13page4/sect13page4.html Recent versions of the core code (I forget exactly when I put it in) allow the sim developer to impose differential limits, both upwards and downwards. The list of train codes has to be built into the core code, so I put in every case that I'd come across, plus a few spares. Any train can be given any combination of codes. The developer will need to document the restriction codes that are used in the simulation. Any code that isn't used is simply ignored, so if there's a "MGR or WES" limit on a piece of track, it won't be affected by selecting "EMU" or "TGV". The idea, as always, is to provide more realism. As to the specific ones you ask about: MGR was used between Ferrybridge and Milford Junction Class 67 ("CS"  is in the rulebook, though I've never personally seen one373 ("TGV" was used just north of Hitchin and just north of Huntington, where the shoegear could foul a particular line underbridge if the train swayed enoughMetro is to allow simulations to impose LUL etc. specific limits Tripcock is used in Wembley Suburban and will be used in Euston, where certain sections of track have lower limits for trains not fitted with tripcocks.

" said:Class 67 ("CS"I can't find any documentary evidence but I have it in the back of my head that when first introduced, Cl. 67 had a lower speed limit over the King Edward Bridge between Newcastle and Gateshead due to the high axle loading. On the line jointly used by conventional rail and the Tyne and Wear Metro between Pelaw and Sunderland, there are actually 3 speed limits applicable over each stretch for (in broad brush terms) DMU (in mph), freight (in mph) and Metro (in kph). “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 |
