The only two times that I saw 31101 on the national network, it was running light engine. Not usually worth a picture, but I thought this broadside view of the loco passing Winwick on 12 March 1990 was noteworthy, as it shows off the loco's unusual livery. The grey roof looks smart, but the red stripe only going as far as the cab doors looks a little odd. Also, the slightly truncated BR double arrow logo is even weirder!
