Yes, Togo, the A1s appeared in four different liveries when they were running in regular service. The “A1 Locomotive Trust” (which built the engine from scratch) promised Tornado would carry all four of the livery variations during its first period of operation.
Following its initial debut in ‘works grey’, the first proper livery carried by Tornado was apple green. This was changed to BR green (a darker shade) in early 2011 when the locomotive returned to service following remedial attention to the boiler in Germany. The change to express passenger blue was undertaken at a works in Southall during Tornado’s October-November 2012 winter maintenance.
That livery remained for only around 18 months. The Tornado ‘brand’ is very much as an apple green locomotive and this will remain her ‘core’ livery”. Apart from the various colours there were also variations in emblems and lettering on both the locomotives and their tenders and these have also been displayed at various times by Tornado.
