If feel like having sparks should a fundamental feature for electric trains in TSW2. So with that being said, here's how I think it should work for both 3rd rail and overhead wires. 3RD rail: 3rd rail sparks should be drynamic to which side the 3rd rail is on, and have different varieties in size of sparks defending on the speed of the train and the weather conditions you set, this would be the same for overhead wire as well. -weather such as rain or snow should have an increased chance of sparked occurring. -depending on the intensity of the snow/rain would lead to different sized sparked coming from each shoe. Pantograph/overhead wire: -the overall likey hood for sparks occurring should be decreased. -the likely hood of sparks occurring should be slightly decreased because the pantograph runs under the contact wire, unlike the shoe for the 3rd rail. -in harsh weather conditions the same treatment applies to the likely hood of sparks compared to 3rd rail. - when raising/lowering the pantograph, small sparks should also be present. -special cases should also be applied to dual voltage trains like the class 395 including but not limited to the TGV duplex, 3rd rail sparks should be present at a low likely hood when raising or lowering the shoes. I think the tech is already in place for this to happen, it just needs to be implanted, and I hope it does soon. This would improve the immersion and make it more realistic.
