Smaller "train station" for use as waypoint only

I think it would be useful to have a smaller "train station" that can be used only as a waypoint.
It would enable players to build smaller train yards for train parking, should they want to, and look nicer if players desire waypoints for whatever reason on their tracks.
With the current train station, I would have to have a gap of 5 tiles between each railway in a yard, which is quite large considering the normal compact nature of rail yards IRL.
Something smaller, with just the space for the signpost (max one or two tiles) would be ideal if it could mean a "quick" modification to the current model

In addition, these "waypoint" stations should not slow down trains should they be able to proceed to their next station, like the current stations do, if possible

I'd love an inline train station (maybe with a 1 tile wide railside building to hook belts to) that can be used for loading/unloading, it could be attached to belts or external storage for loading and have no storage buffer.
