An unidentified ex-LMS 5XP 4-6-0 Jubilee class locomotive is
seen at the head of a named up express train as it crosses over Humber Road
junction. The upper quadrant signal seen behind the signal box has replaced the
lower quadrant signal seen in the earlier views. The upper quadrant signal
operated with the arm being raised above the horizontal by 50 degrees whilst a
lower quadrant signal operated with the arm being being below the horizontal.
This change of practice was initiated because of an accident caused by snow
jamming a lower quadrant signal arm which prevented it from returning to the
horizontal - the danger position.
