[[File:Parr_Wagons_20180602.jpg|tuumb|300px|right|Parr wagons DC967577 (nearer) and DC967526 at Bewdley, June 2018.]]These vehicles are YQA 'Parr' Bogie Rail Wagons (Borail). As the name suggests, these were designed to carry rail with the load secured using lashing rings mounted on brackets on the solebars.
==Service==BR 's Derby works<ref>[http://paulbartlett.zenfolio.com/brborail Paul Bartlett photos]</ref> built 165 Bogie Rail Carriers, TOPS code BRV, in the early 1960s. 30 were built rail carriers to diagram 1/482 and 135 wagons had a flat deck for carrying concrete beams, while the rest were constructed built to diagram 1/483and were equipped with five tall bolsters for carrying rail. Under TOPS Both designs had vacuum brakes, 'fish-belly' solebars (deeper between the bogies) and lacked any bodywork above floor height. Loads were secured using lashing rings mounted on brackets on the Borail solebars. The 165 wagons were coded as BRVnumbered B946065 to B946229<ref name=LTSV>[http://www.ltsv.com/w_profile_034.php LTSV Wagon information 16 March 2010] (retrieved 16 December 2017)</ref>, the vacuumB prefix indicating an BR era wagon used in revenue-braked variantearning service. This was selected for upgrade work and in In 1981 lot Lot number 4012 was issued for conversions to upgrade 150 of the BRVs at Shildon works. Besides the modifications to the brakes and the fitting of new Y25C bogies, the body was altered to have 8in tall sides and ends, each side having 6 cutouts for strap tensioners. The lashing rings were removed but the brackets were left in situ, and six new bolsters were fitted. The rebuilt wagons were given new numbers 967500 to 967649, TOPS code BRA and design code BR006A. The last BRAs had perhaps the shortest life in original use of any wagon type. The last were completed in January 1982 but, . However by early 1983, the whole fleet was had been transferred to departmental Departmental use . DC prefixes were added to the wagon numbers and recoded the wagons re-coded YLA (YLA-B) to design code YL003A, and gained DC prefixes. To A further change of TOPS code to YQA took place in 1990 to avoid confusion with the YMA Salmon fleet, the TOPS code for the Parr wagons was changed to YQA in 1990<ref name=LTSV/>.
== Acquisition and use by the SVR ==
For many years, SVR P-Way trains used wagons fitted with vacuum brakes. In more recent times air-braked stock such as the [[BR 'Rudd' Ballast Wagons | 'Rudd']] and [[BR 'Seacow' 40t Bogie Ballast Hoppers|'Seacow']] ballast wagons have been acquired, with the introduction of these two similarly fitted rail / sleeper carriers following this pattern. The Traffic Notice for 21 November 2017 showed a Class 66 locomotive was to bringing bring two wagons from Bescot. The move was cancelled due to no DBS Cargo driver being available. They were finally delivered on 14 December 2017 by locomotive 66066 and tripped to [[Bewdley]] by local arrangement using visiting locomotive [[33108]], which was in use on engineers' trains.
