Modifications

Most of the engines were modified by fitting larger water tanks. This increased the total capacity from 1,371 to 1,630 imp gal (6,230 to 7,410 L; 1,647 to 1,958 US gal). 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]
