Preservation Information
51043 was one of the last class 126 sets in service when withdrawn in January 1983, and was preserved as a historically authentic 3-car set with partners 59404 &51017 by the Swindon Diesel Preservation Society who based the set at the Caledonian Railway.

The set, by now unique, was contaminated with blue asbestos and in poor condition, however the SDPS returned the vehicles to service and repainted 51043 into BR Green during the late 1980's.

All three vehicles including 51043 were sold to the Scottish Railway Preservation Society in 1993 and moved to their base at the Bo'ness & Kinneil Railway.

51043 did some limited passenger running at the 1993 diesel gala and was then withdrawn from service, being stripped of its asbestos the same year. A mechanical work week in May 1996 enabled the vehicle to run at the diesel gala the following month, the first time since 1993 that the vehicle had operated passenger services. However a full rebuild was required to reverse the damage done by the asbestos stripping and also to tackle th badly corroded bodywork.

The vehicle was repainted into BR Blue in 1998.

2000-2002 saw a false start in the form of a contract restoration at Lancastrian Carriage & Wagon in Heysham. The bodywork undertaken was not satisfactory and the vehicle returned to Bo'ness very much incomplete.

In 1999 fortunes finally turned with a sucessful £180,000 lottery fund grant for the full restoration of 51043, 59404 & 51017. This was completed both at Bo'ness and by contractors at the Midland Railway Butterley where 51043 was sent between 2005 & 2006.

In 2008 the 3-car set was launched into passenger service concluding the sporadic 20 year restoration. Due to the funding grant, this time the overhaul was very thorough with 51043 becoming one of the finest restored DMU vehicles in the UK.

2009 saw the interior painting and restoration of the guards area inside 51043 completed.

Since 2008, 51043 has seen limited use at the Bo'ness & Kinneil Railway, as the vehicle is not in front line service in order to preserve its condition.

In July 2011, the SRPS completed a rolling stock shed designed to house, amongst others, the diesel and electric multiple units in their collection, giving 51043 a future undercover. The same year saw the batteries replaced, however in October the set withdrawn from service due to 51017 suffering an engine failure.

2012 saw the letter rack, which was missing from the brake van, remade to the original design and installed. Refurbished cab windscreen roller blinds were also fitted.

In May 2013 when a replacement engine was fitted to 51017 allowing the set returned to service.

51043 remains in good condition and operates occationally at the Bo'ness & Kinneil Railway. The vehicle is not in very regular use, in order to preserve its condition.
