Hi Tom!
It's a mixture of Swiss made FAMA and Austrian made Roco Alpinline in 0m. Metre gauge in a scale of 1:43. This stuff has a long and tortuous history, starting off as FAMA in the early 70s, then it became UTZ and then Golden Trains, and finally it was bought out by Roco in the 90s, but they discontinued it after a few years. It's now available from another Swiss company (still called Alpinline, I think), but at a horrendous price! It became two to three times more expensive. What you see will be some of the stock for a new layout, featuring rack track etc;.
