In 1945, the Pennsylvania created a lightweight 50' boxcar unique in appearance, all welded and with slightly excess height, the X41 series. The use of sheet steel only .07" thick welded to vertical posts every 2' yeilded a car side with a mass of wrinkles. The interior height of 10'8" added to the massive appearance. The X41's were the PRR's last major home design.

The X41
The 300 X41 cars had double doors.

The X41A
The 200 X41A's had double doors with an end door to facilitate the loading of automobiles, prior to the advent of bi-level and tri-level rack cars. By the early 1960s half of the X41A's had been rebuilt into X41D's and X41F's.

The X41B
The 1500 X41B's had single doors.
Within the second order of X41's in 1947, were 300 cars specifically for less-than-carload (LCL) service. These X41B's got Steins load retainers, an interior rack system that protected mixed cargo from the damage of stacking and of shifting enroute. For advertising purposes, the LCL cars got a board aluminum band, bordered above and below by white stripes. The circle keystone was dramatically enlarged and given a bright red background, aluminum border, a white keystone and red PRR monogram. In the left side band were the words "Merchandise Service".

The X41K
One hundred twenty-two X41B cars were converted to class X41K in 1966. Side sills were reinforced to handle heavier loads. The roof walks were removed and the side ladders were shortened.
