Make train path visualization not obscure other trains

[robot256]

Currently, the visualization for a train's planned path is nearly as wide as the visualization for the train itself, and fully opaque. When the train you are riding/selected is stuck behind another train, you can barely tell--it mostly looks like it is stopped for no reason.

It would be great if the train path visualization can be made narrower or semi-transparent, so that you can identify other trains while they are blocking your path.

Another suggestion in the same vein - make path segments current signal-colored (like the in-world arrows on top of rails) so that it is immediately obvious that some parts of the path are blocked regardless of the cause.
