Thanks for the response.
Actually, I didn't need to register to get the crossing plates. I just clicked the link in Ryan's original post in that thread below his screenshot and got the CDP.
One thing about those crossing plates is that they use gigantic 4096 x 4096-pixel texture maps in BMP format for the crossing plate, each having a file size of around 64 or 65 MB, with most of the contents of those maps being blank black space, shooting the asset's size to insanely huge sizes such as around 80 MB for one and 140 MB for the other.

They caused CM, etc., to send my RAM usage to 99% when committing those assets I believe. I opened those maps in IrfanView and resaved them in JPG format with the quality level at 100%; the JPG images have a much, much more sane file size of around 1.08 to 1.56 MB each. The crossing platforms do look great in Trainz; thanks Ryan!
Great work reskinning those BNSF50 crossing signals. They are good enough to pass as new crossing signal models.
