Click on the pictures to enlarge.    Roco MZ 1401 runs like a dream. It has a faint roumble (50 Hz) at slow speed, but otherwise noiseless.    Roco BR290 runs like a dream. It staggers at lowest speed but runs fine otherwise.    Roco 45335+36+37 consists of 3 red DSB coaches. 2 passenger coaches with different numbers + 1 coach. They are nicely detailed. I have made the interior lightning myself. I forgot to have them with AC-wheels, but the dealer replaced them at no cost. The models are in scale 1/100, but it suites me fine as I have some R1 curves.    Märklin 37670 consists of two danish NOHAB MY. One brown-red and one black/red. The models is entirely i metal and runs really well. I have set max. speed to 50%. That fits better to my small layout. The sounds is very high, so I have set it to 30%. The sound sounds like a real MY. There is a small delay when starting to allow the engines to start up! The only small complaint is that there is no room for a drivers cabin.
