Modifications

Most of the engines were modified by fitting larger water tanks. This increased the total capacity from 1371 gallons to 1630 gallons. Three engines still had their original tanks at the 1923 Grouping.

Air brakes were fitted to 10 locomotives between 1900 and 1923. The same engines received vacuum brakes as well, between 1928 and 1931.[1]

Use

The N9s were used on local goods trains.

Seventeen locomotives passed into British Railways ownership in 1948 and their BR numbers are shown in the table below.[2]
