Station bridge plates - Know where I can find them?

[Scottbe8]

I'm looking for the platform bridge plates that stations in the northeast use when the outermost track(s) are out of service. An example can be seen in this video: due to tie replacement on the southbound track, NJ Transit is using these bridge plates at Metuchen, Edison (depicted), and New Brunswick.

If this has been made for Trainz, where can I download them?
