The performance objectives set for the class XP were running mileages of 200,000 mi (320,000 km) between overhauls, and a monthly average mileage of 10,000 mi (16,000 km). Both of these objectives were very ambitious for the time.

The basis for the class XP design was the boiler and firebox of the XB, with some modification to their details. The wheels and cylinders of the two classes had the same dimensions.
