SR Maunsell carriage

Construction

In 1925 the first order was placed for the first Maunsell carriage. The coaches were 59 ft long with a width of 9 ft 3in and a height of 12 ft 4in. The bogies were SR bogies with an 8 ft wheelbase. The third class compartments were 6 ft 3in. wide seating 4 a side, while the first class compartments were 7 ft 1 ³⁄₄ in. wide and seated 3 a side.

The body frame was mostly made of wood with steel sheeting, the roof was made of wood with canvas over it, the guard and luggage compartments had a width of 8 ft 7in, with pressed steel duckets between the differences in widths from luggage to passenger compartments. The decision about the gangways was decided in January 1924 with Pullman Gangways being adopted.

In total over 1200 Maunsell Carriages were built with 139 sets being formed.

Early 59 ft corridor stock

The first batch of coaches were built for the West of England as three-coach sets with a third brake, composite and a second third brake being in the set. Ten sets were constructed, with numbers 390-399. The first batch was completed in October 1926. The seating capacity for a three-coach set was very low with 24 first and 88 third seats. After the first batch orders for a total of 16 sets were completed by 1929.

59 ft corridor stock 1929-1934

In 1929 Maunsell modified his design to have high corridor windows, but the corridor windows at the ends of the coaches remained the same height to allow a destination board to be attached. The design was authorised in April 1928 and the first order was for the Hastings line which required the coach width to be 8 ft 0  ³⁄₄in, this was due to clearance issues. First Class compartments only seated two each side, Third Class three each side and roof board brackets were above the rain strip. Also in the order were coaches for the Folkestone line which required a width of 8 ft 6in. Between 1929 and 1934 a total of 77 sets were completed by 1934

Later 59ft corridor stock

In early 1933 Southern Railway announced that 1065 Maunsell carriages were built. Most of the carriages built after 1934 were flushed sided and each toilet now had two sliding ventilator glasses, there were a few other minor alterations. Forty-six sets were built.

Maunsell Post Office vans

In 1923 the Southern Railway inherited two main TPO services from the London and South Western Railway and South Eastern and Chatham Railway. The services were provided by pre-grouping carriages, but in 1936 a pre production model No. 4919 was built and an order placed in 1939 for a Maunsell-designed Post Office sorting van (POSV) with two types: a sorting van of which four were built (including a pre-production model) and a tender van (POTV) of which four were built; they both have offset gangways.

In preservation three examples survive, two POSVs, 4922 at the Bluebell Railway and 4920 the Nene Valley Railway, and one POTV, 4958, at the Pontypool and Blaenavon Railway.

Maunsell push-pull sets

In 1959 British Railways (BR) started to convert 20 Maunsell brake composites and open seconds. The brake composites in each set had the lavatory sealed off and the gangway at the brake end removed. A driving end was provided with two small windows fitted overlooking the track. The Open Seconds had their lavatories removed and sealed off and gangway to the locomotive end removed. The sets were numbered 600 - 619.

In preservation two driving brake corridor and an open third survived, No. 6699, 6697 and 1323, all of which are at the Swanage Railway. The Swanage Railway want to create an authentic push-pull set with 6699 and 1323, forming Set No.619.

Southern Railway use

The first sets that entered service in 1935 were assigned to the west area of the network and gradually spread all over the network, The Maunsell coaching stock gradually replacing old pre-grouping stock. The coaches were always operated in sets with loose stock placed in sets when carriages were in overhaul.

Accidents involving Maunsell-built coaches 1927-1947

During World War II between 1940 and 1944 16 Southern Railway-built coaches were destroyed in a number of different raids, many more were damaged but repaired and returned to service.

Liveries

Maunsell stock in Southern Railway had two main liveries the first was introduced by Maunsell and lasted to 1939 before Bulleid modernized the coloring in 1940.

British Railway use

The policy under which the Southern Railway operated set trains continued into the Southern Region of British Railways; sets were disbanded and created as British Rail (BR) tried to create a new timetable. Since 1949 the official livery for all main line coaches had been crimson and cream, in seven years the whole of the Southern Region fleet should be crimson and cream but that wasn't the case as many sets were still in Southern Railway malachite green. In 1959 as the Kent Coast electrification scheme was completed most restriction '0' were withdrawn at the same time. This decline continued as BR had more modern Bulleid and mark 1 coaching stock until 1967 where the last was withdrawn. Many Maunsell coaches were sold by BR to heritage railways were they restored and operated.

Preservation

The carriages are well represented in preservation, with 33 preserved on heritage railways across the country. Two driving brake composite, four corridor composite, five brake third corridor two are under frames, one dining saloon, one kitchen first, two brake corridor composite, four brake unclassed open, five third open, two Post Office sorting van, two corridor third (one is an underframe), one corridor first under frame, one open second under frame, one Post Office tender van, and two unknown underframe.
