The stake cars were also redesigned in the mid 1920s in accordance with the principles of interchangeability. It was decided to use the chassis of the Gl car so that the car was longer than its association type predecessor and had two more stakes. However, the larger loading surface did not affect the payload; this remained unchanged at 15 tonnes. As the majority of freight transported generally had a high volume and a low weight, this had no further negative effect. As with the freight carriage, the majority of the stake cars could be adapted to the Russian wide gauge in accordance with the spirit of the age and identified by the white buffer sleeves and the sub-class mark "r".
