Trying to find signal boxes equipped with EIT

[jordon412]

I know that there was a series of signal boxes equipped with Enhanced Interlocking Tower (EIT), but I cannot find them. They look British in appearance, which is giving me problems as I cannot figure out what they are named. I've downloaded them previously, but I can't find them now. Can I get some help finding them?
EDIT: Just found them. I thought they were made for TANE, but they were made for TS12, which I didn't have the checkbox checked for, until now.

If you use the Enhanced TRC3 invisible interlocking tower, by pguy <kuid2:61392:8101:78>, you can place it anywhere, such as next to a more prototypical signal box scenery asset. It will only be visible in Surveyor.
