Perhaps as an option for electrified tracks or any tracks that otherwise require a feature that shouldn't spawn at every block at the track, a part of the track can be labeled something like "SUPPORT_TOWER_X. The X represents how frequent the object would spawn on a segment of track (10=10 Blocks, 20= 20 Blocks, ETC.) In between, the object would not be rendered (Think things like Particle Cubes) This would be good for wire support towers for electrified track, or as a support on a bridge. Even if electric locos aren't properly implemented yet, it would still be a good cosmetic feature to have.

I hope it can be combined with the electrification system of Immersion Engineering, the power of diesel generator can be used to supply train operation, and the electrification accessories of Immersion Engineering style can be added.
