The Grampus wagon was the principal open wagon used by BR from the 1950s until the early 1980s. Their design incorporating three drop down sides and removable end planks made them very versatile and enabled them to carry everything from ballast to signal posts. Many thousands were manufactured covering several design patterns and could be seen singularly or in block workings across all regions of the BR.
