Quote from: SuperTimo on October 17, 2018, 03:18:02 PMFrom someone who works in railway signalling In real life I can't think of any passenger lines that are limited to 75 Mph in the UK for their entire length. Speed profiles are not usually decided by track quality instead, as is the case in-game, the quality of the track is more a factor as to which rolling stock can use a line. So you might have a line that has a 75 Mph speed limit because the only rolling stock intended to use the lines are class 14Xs (pacers) which have a top speed of 75 Mph so the signalling is only designed accordingly. All of those locomotives you cannot select are heavy freight or express locomotives and so would be completely unsuitable for the type of lines you are talking about. These low speed lines are normally only as such due to the geography of the routes they take, for example lines in Cornwall. Most freight trains are limited to a maximum of 75 Mph regardless of what line they are using (I think goods vans can travel at line-speed but these are very rare in the UK today, container flats are only permitted at 75 Mph), some freight only lines may have very low speed limits since they are only used by one train at a time and a lower speed limit prevents wear to the track, in which case the speed limit would probably be as low as 20 Mph, which you can represent in game by using drive by sight working.
Quote from: SouthernTransport225 on October 17, 2018, 03:43:14 PMOkay true, but ignoring the fairness thing (James). I do want to run loco-hauled trains but with the track weight being to heavy. Its not possible, particularly when your trying to be realistic;y recreate the exact service with the exact loco/wagon/carriages.
Quote from: SouthernTransport225 on October 20, 2018, 07:50:02 PMOkay I understand what you are saying, but my point is that I want to have loco hauled passenger train/freight services using the locomotives and wagons which are too heavy for the 120 km/h (75 mph) track. However, one suggestion that I am putting forward (may need a new topic for this) is to have different types of track with different speed limits (e.g. 26 tonne track with a max. speed of 75 mph (120 km/h) or 22 tonne track with a max. speed of 105 mph (168 km/h))
Quote from: jamespetts on October 20, 2018, 08:56:15 PMIs there any evidence that such track existed?
Quote from: ACarlotti on October 20, 2018, 09:22:47 PMI'd have thought that it could be the same track but with different speed restrictions for different types of train. It very common in the UK to have different speed limits for multiple units and other trains (or some other partition of the stock into two groups). I imagine this would be because some stock imparts a lower dynamic load on the track (for a given speed) and can hence be run at a higher speed without damaging the track. The most obvious reasons for this would be either a lower weight (axle weight in particular) or better suspension.Of course, this is a little different to what is being asked for.
