1/ British railways continued to build non-corridor stock into the interwar years, this coming to dominate suburban routes, whilst corridor and saloon coaches were found on main line services.

Non-corridor stock continued to be somewhat austere and much complained in many

2/ places, but was retained on suburban lines because of its high capacity and the fact there was no requirement for on-train facilities, given the short distance between stations. There was, however, one notable experiment in improving ride comfort over the older types;

3/ Gresley& #39;s articulated non-corridor stock for the Great Northern Railway, shown in the first image in 1914.

These sets would later be rebuilt into four-coach "quadart" sets. Having a high capacity, they would continue in traffic until the 1960s. However, non-corridor stock

4/ lasted much longer elsewhere. As late as 1991 one MP reported in the House of Commons the presence of such stock on the Ramsgate to Cannon Street services.
