In 1900 the majority of GER suburban trains were composed of four-wheeler carriages.

Interior design was spartan and around 1900 third-class passengers sat on bare boards five abreast, second-class passengers on cushions also five abreast, while first-class passengers sat four abreast and enjoyed more legroom.
In 1899 James Holden produced the first six passengers sat abreast carriages in a 13-carriage, third-class only train (each carriage was 27 feet (8.2 m) long and 9 feet (2.7 m) wide and had five compartments).
This set, which also included such modern features as slam lock doors and gas tail lamps became the model for future suburban carriage design.

In 1899 Holden built the first GER all-bogied suburban train and although a success, the next one did not follow until 1911.

The GER made every effort to maximise the capacity of its suburban carriages to deal with the rise in usage.
In the early 1900s some four-wheeler carriages were cut in half longitudinally and a section inserted to make them wider in order to increase the capacity.

More bogied suburban trains followed in 1911 and were deployed on the Ilford, Gidea Park and Loughton services.
By 1915 A. J. Hill instigated a policy of converting old four-wheel carriages into bogied stock and some 500 four-wheeled carriages were converted this way.
The GER had a reputation for doing things on the cheap and this certainly was cheaper than building new stock.
