I exposed these photos with my Fuji X-T1 a little while ago (7 March 2015). Compare these photos made in soft afternoon sun with my image of the same freight train at the same location last Saturday (28 February 2015)
Locomotive 071 is the class leader; one of Irish Rail’s 18 General Motors-built model JT22CW dual-cab six-motor diesel-electrics.
Sun = good !
