598:) passenger locomotive with a 17-long-ton (17 t; 19-short-ton) axle load. It had a lot of problems. It was built with the help of British Engineering Standards Association (BESA). It was up to date as any locomotive in England. It had American 3-point suspension with compensating levers for indifferent tracks in India. The trailing wheels were mounted on a Cartazzi truck as it was for the rest of British Pacifics at the time. Goodall-type drawgear was fitted between engine and tender to facilitate free movement. They still proved to be successful as they survived till the 1980s. The modifications in India to this class was implemented in

696:. Tube cross-section area to the grate was only 9%. The boiler was poor, having pressure below 150 pounds per square inch (1,000 kPa). Testing showed that the engine was unable to haul a 350-long-ton (360 t) train at 60 mph (97 km/h) at 33% cylinder cut-off. It oscillated laterally at a right-angle to the tracks causing damage to the tracks. In 9 years, there were 68 such cases due to XB and XC class locomotives.

The trailing bogie was moved 30 inches (760 mm) back and engine was fitted with
American drawgear. But this did not work. In 1937, the Bihta accident occurred with the engine jumping the tracks and derailing at 60 mph (97 km/h). The tracks were twisted like noodles. 100 people lost

their lives. The
Pacific Locomotive Committee was formed on public demand. Robert Leguille came up with a solution. He decided to fit leading and trailing bogie with stiffer side springs and better damping. He was proven right with experiments. The
