Does Trainz just not support more than one speed on a section of track?
Around Seattle here we they use 3 Speed sign, 1 for Freight, 1 for Passenger (Read Amtrak), and 1 for Transit (Specifically the Sounder, which runs up to 65 MPH almost the whole way into King St Station).
Consider this asset:
Update max speed and priority,<kuid2:645812:100106:5>
Play the trackside asset a few meters behind the speed sign and configure it to whatever you like to have what maximum speed.
Will check for:
- Load (not relevant / at least 1 car loaded with...[specific product] / no cars loaded with...[specific product])
- Train control (AI / all)
- Name of the front engine;
--- Prefix (same as, not the same as, not relevant)
--- Postfix (same as, not the same as, not relevant)
- Current prio (1-3 / not relevant)
- Same direction (Yes / not relevant)
- Consist build-up ( engines only / empty cars / at least 1 loaded car / not relevant)
Maximum speed will only be adjusted downwards.
If the driver is not in the front engine or the front engine is not at the front, the adjusted maximum speed will not show but the AI train will respond to it.
