It's a sign of desperation when you start photographing light engines but, on this occasion, I couldn't resist the patterns of light in the sky. JS 6225 climbed from Shenxi towards Mine 1 at dusk on 6 January 2005. During our visit, the diesel seemed to handle most of the traffic on this steeply graded branch, leaving few opportunities to photograph steam on one of the system's best climbs.
