Virginian Class XA
Built in 1916 by Baldwin, this locomotive is different than the Erie Triplex, while it is a triplex, it was a 2-8-8-8-4 (Unlike the MTH Model of the Virginian Triplex, which reuses the Erie Triplex body). The Class XA was cut into 2 separate locomotives in 1920, becoming a 2-8-8-0 and a 2-8-2, both of which were in service until 1953, with the 2 being scrapped.
Keep Infinity Electricity on, keep engine overheating off and it’s optional if you want Infinity fuel on.
