New Railtype Label Scheme

[McZapkie]

I'm little bit confused with proper naming of track label. How should be properly named tracks with 25 kV catenary and speed limits 160 and 300 km/h?
SDAA and SEAA (there are also track lower than 160km/h in my newgrf, but not electrified) ?

Probably, yes. Make sure to include `SAAA` in the `compatible_railtype_list`, though.

Assume that there are 3 different voltage systems: SAAA (25kV AC), SAAa (15kV AC), SAAD (3 kV DC) and additionally multisystem track - just generic ELRL.
I want to allow 25 KV locotomove to be powered by 25kV or multisystem track, etc, while multisystem locomotives can go everywhere.

How to correctly define it?
powered_railtype_list in track nml file should have only native catenary, or both native and multisystem, while locomotive track_type is defined as 25kV only,
or alternative multisystem should be defined in vehicle section?

SAAA should have ELRL in its powered_railtype_list, SAAa+SAAD+ELRL+RAIL in its compatible_railtype_list, and RAIL should have SAAA+SAAa+SAAD+ELRL in both compatible_ and powered_railtype_list, and ELRL should have SAAA+SAAa+SAAD in both compatible_ and powered_railtype_list and additionally RAIL in compatible_railtype_list. Then on the locomotive you set tracktype to SAAA for 25kV AC locs and to ELRL for multisystem locomotives and RAIL for wagons.

Thanks for reply. But why unelectrified RAIL should have catenary tracks in powered railtype list?

The powered railtype list indicates what tracks a train with railtype RAIL can run on. RAIL vehicles can run on catenary tracks, so they should be in the powered railtype list.

I assumed you want vehicles that run on tracks without catenary to also be able to run on tracks with catenary. By default RAIL has only ELRL in its lists, but as you are introducing additional tracks, you also need to update RAIL to also allow running on those tracks if that is needed.

[McZapkie]

Oh, I see, it is just to ensure that steam/diesel can run on electrified tracks.

Steam, diesel, but also wagons, to ensure they can run on your tracks. That is also why you add RAIL to the compatible_railtype_list of your tracks, so that engines can be push/pulled on those tracks. Because you are also reusing ELRL as a multisystem track that can also run on your tracks, you need to add RAIL explicitly in the compatible_railtype_list of ELRL so that it behaves as default OpenTTD again.
