A spectacular sight (and sound!) at Burrs on 12 September 1999, as 37906 Star of the East, 37029 & 37351 pile on the power as they climb away from Bury with the 17:10 service to Rawtenstall, during the East Lancashire Railway's 'EWS Classic Traction' event. All three locos are producing plenty of clag, but 37351 is the star performer in the pollution department. For some time it had been noted for its displays of soot production, much to the delight of photographers, but not environmentalists!
