D1661/ 47840  North Star.

The loco came to us back in May 2007 for preservation and has worked on the line ever since as a regular reliable
performer.

Here are some photos of that major day:-

Final Mainline service:-

The loco was used extensively to move refurbished HST power cars and trailer vehicles around as part of the overhaul
programme. Most of these moves happened on a VSTP basis (Very Short Term Planning) arranged through First Great
Western control and Network Rail as required. This resulted in some very interesting colourful combinations running
around the network! The loco was also extensively used on shunt release duties between Paddington and Old Oak
Common for the Sleepers in its final mainline days.  On Monday 30th April 07 the loco went Light engine as 0Z47 the
1130 Old Oak Common to Loughborough for work to be done on it before it enters preservation.

gal coolant capacity   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.
