These things work great and would recommend them. I have purchased two sets now (one for me and one for a friend). Would recommend you consider a longer version as well for longer passenger heavy weight coaches.
Also have you ever considered ( we have talked about it) offering these in HOn3 (both single and dual guage), they would make life so much easier to load rolling stock and engines and there are many modelers I'm sure would agree after trying these. I highly recommend them! Thanks!!!!
