[1] Large numbers of the NER G6 0-4-4WT class were made redundant during the 1890s.

Forty of these were rebuilt as 0-6-0T shunting locomotives at York Works between 1899 and 1904.

This fitting was usually accompanied by the addition of carriage heating equipment.

They were used for general shunting and marshalling coal trains.

Withdrawals started in 1933 but 45 survived into British Railways ownership in 1948.
