The NSWGR 32 (originally P pre 1924) class is a 4-6-0 steam locomotive built between 1892 and 1911 with most staying in service until December 1971.
The locos were well respected by all locomotive crews as they would rarely fail and were excellent steamers. Originally built for express trains they were later used as mixed traffic due to larger express locos entering service. They would often be seen on branch lines doing mixed goods, passenger runs, being used in mainline yards as shunting locomotives or sometimes being used on mainline passenger and freight.
As I have an access to and also work on the real thing I would be more than happy to help with any reference photos and information.
