Ok, First off... this was the first signal I ever purchased, well I purchased it in an order with the dwarf light signals. This only works with Marklin C track and you can't wire it up to an atlas 200 snap switch. So I removed the marklin stuff and used my own because this is a good looking block signal. If I had the money all my switch indicators, and block signals would look like this. I don't know why but it just looks so damn good. I would actually buy another one just to hack it and put it on my layout as a switch indicator. Its pretty detailed, and pretty sturdy. I think I want one of these for my MOW siding.
