Allow electric energy_source for locomotives

[DylanDerEchte]

I'm currently working on a mod which aims to add in new Trains which run on electricity delivered by poles and substations in order to make them more similar to the german train network and I've come to the problem that the locomotive prototype only allows burner and void energy sources. Would it be possible to lift this restriction?

Sorry but no. The performance overhead for trains to use electricity would be unacceptable. Every tick every time they moved they would need to scan a *huge* area around themselves to disconnect and reconnect to electric poles and that's not acceptable.
