It's very very rare for diesels not to be allowed to take any route for reason of being a diesel as they have their own power supply. Peter I identify as half man half biscuit - crumbs! Log in to reply |

I believe the few cases that exist are due to confined, poorly-ventilated tunnels - Moorgate and Woodhead come to mind. Diesels did occasionally use Woodhead, but it was officially discouraged and a strict spacing between diesel-hauled trains was imposed. There are also places where diesel locos are banned but DMUs are permitted - this tends to be due to weight problems. In some of those locations Class 37s are specifically exempted from the loco ban, because they exert unusually low track forces for a loco. In the days when the common-carrier freight obligation still existed, power-twin DMUs were used to haul small loads over those lines. Neither of these cases applies to the Salford area. Restrictions are more widespread on steam locos these days. Smoke emissions are considered a much bigger problem now than they were 80 years ago, and loading-gauge restrictions have developed to accommodate bogie stock much more easily than a kettle's rigid, overhanging frame. Class 9F is outright banned from the mainline (even if hauled dead) because its flangeless centre drivers are incompatible with modern guard rails which are raised slightly above the running rail. Etc, etc. And, obviously, an electric train can only traverse a line with a compatible power supply. I understand the two 1500V systems covering Woodhead and Altrincham were physically separated by the 25kV AC system coming from the WCML, which must have made things very interesting at London Road.

Perhaps I should clarify what I meant above. I queried the point years ago because there is no option in the core code to inhibit diesel power using a piece of track. The answer being, that because the power restrictions on SimSig is intended to be a physical one rather than one of policy. So because a diesel train has its own power supply it can literally go anywhere. What can be done is enforce a policy restriction through bespoke coding, perhaps by applying a penalty, or a 0mph speed restriction based on power. Peter I identify as half man half biscuit - crumbs!

It would be a real surprise if all TPE and Northern Drivers did not sign the route. As this chord will become part of a standard diversionary route most companies will require drivers to learn the route.As with all these things some drivers often through no fault of there making will miss out and this will produce problems.
