@Delia - They are Trainz 1.3, and coming up fine for me on the TRS04 DLS page. Try kuid 9000:27410 and download the pack.
@kevaylett - They are by me, and will be released in the next few weeks. They are based on the tramsignal mesh from Andi06's crossings, but enlarged to regulation size, and with individual coronas for each LED. They come in left and right hand versions at various offsets from the track, and also include diverge versions.
