lavatory at each end Although designed for long-distance operation, the "Laminate" stock was extensively redeployed on Dublin and Cork suburban services in the 1970s and 1980s as newer rolling stock became available. This was not ideal due to the layout of the carriages and limited door openings, which resulted in longer dwell times at stations. Following the Buttevant crash in 1980, the "Laminate" and Park Royal stock was restricted to a 70 mph top speed and later banned from certain routes. After the electrification of the Howth-Bray route in 1984 and the introduction of Mark 3 stock, the "Laminate" stock was progressively withdrawn. Some have been preserved at various locations around Ireland: Downpatrick & County Down Railway has Buffet Car 2419 and Brake Standard 1918TL (orig.2163) . Kiltamagh Museum has Standard Open 1460 and Composite 2148 The Railway Preservation Society of Ireland in Dublin has Standard 1463, Bar Car 2421 and Brake 3rd 1916. The RPSI also owns Buffet Car 2422TL, which is on display at the Ulster Folk and Transport Museum. Sligo Folk Park in Riverstown has Standard Open 1468 Park Royal (1955–1994) In 1955 Inchicore Works commenced the construction of 50 coaches from parts supplied by Park Royal Vehicles, London. These coaches were produced in Main Line or Suburban variants, and made full use of the Irish loading gauge, being 61 feet 6 inches long and 10 feet 2 inches wide, reducing by 8 inches at their ends. Because of their aluminium and steel construction, they weighed only 26 tons tare (Suburban) and approx. 27¼ tons tare (Main Line). Unusually, these coaches had inward opening doors, similar to the American "Pullman" design, but this proved unpopular and somewhat confusing to the passengers and so were rebuilt conventionally. The suburban coach seated 82, while the main line coach, fitted with lavatories, seated 70 passengers. These coaches rode on Commonwealth bogies, the first in Ireland to be so fitted. Barred from certain routes during the early 1990s because of their construction, the last few Park Royal carriages were withdrawn following the delivery of the first Japanese 2600 Class DMUs in 1994. There are several preserved examples; The RPSI has two, two Open 3rds, Nos.1383 and 1419. No.1383 is fitted with a shop, whilst No.1419 has been modified so as to be wheelchair compatible. No.1944 has been fully restored at the Downpatrick & Co. Down Railway and is now part of
