A few weeks ago my BYLONG layout had an interesting visitor, the engineering sample of the Casula Hobbies Z19.
The model ran very smoothly and is geared down to a very respectable low top speed typical of the prototype. I didn't measure the speed but it appears to be no more than about a scale 40 mph. Slow speed running at DCC speed step one was impressive as well. The detail level is fantastic!
I have the Baldwin tender 1957 with cowcatcher and sound on order for my Cassilis branch line. The branch line is not fenced so the cowcatcher is needed. My Wombat C30T is the current branch locomotive but it doesn't have a cowcatcher, something I may have to remedy in the future.
