Excellent Models indeed Ross.
The 830 Class is the equivalent of the NSWGR 48 Class. Both are very versatile locos, used for mainline, branchline and shunting duties.
My other purchase at the same time I picked up the 44 Class, is the 49 Class. Another outstanding model to say the least and a bargain at $140.00 ! (£68.60)
Apologies for the slightly out of focus pic above.
Now, all I need to do is to dig out some wagons and build a NSWGR based layout. Maybe an Inglennok or something similar...
Cheers, Gary.
