47840 has led a varied life. It was built at Crewe Works and entered traffic on 13th February 1965.
Originally allocated to Cardiff Canton the loco was numbered D1661.
In March 1965 the loco was named NORTH STAR at London Paddington before hauling a special
train to Bristol. Changing between various depots over its life the loco finally became part of the cross
country fleet being converted from a 47/4 to a 47/8 locomotive with larger fuel tanks to reduce the
regularity of fuel top ups. The highlight of it?s career perhaps was the working with 47847 on 19th
August 2002 from Penzance to Birmingham New Street with the last regular class 47 hauled train on
virgin cross country. The loco was repainted into BR blue for the occasion and the final months leading
up to the event. The loco continued to work for Virgin acting as a thunderbird loco and working
weekend drags regularly over non electrified sections of line. It also worked occasionally for other
operators. In August 2004 the loco was transferred back to Willesden depot and into the Alstom
spare locomotive pool. Virgin had finished with the loco following the introduction of Class 57 locos
for thunderbird/drag duties. The storage was short lived however, in April 2005 840 returned to traffic
working for First Great Western on sleeper shunt release duties at Paddington. This was to cover for
lower than expected availability of Class 57s for First which had previously ousted 47s on this job.
Interestingly the loco has carried Dual Green, BR blue, Intercity and Virgin liveries before being
repainted back into BR blue in 2002 for the last Virgin workings. This loco has never carried large
logo livery.
