Running an hour early, 67027 Charlotte emerges from Sapperton Tunnel on 9 October 2021 with the 3S33 10:49 Cheltenham Lansdown Loop to Swindon Transfer Rail Head Treatment Train. 67023 Stella is bringing up the rear. 67027 has already acquired the usual 'RHTT grime' livery, although from other pictures I have seen, this side is somewhat cleaner than the other side. Clearly it is not going to be possible to take pictures of this train at this location for much longer, if the sun is out.
