E56019 and E50019 are seen in Birmingham New Street on September 15th, 1962, forming the 4.23pm service to Derby. The DTC has an unusual shape of whiskers, the DMBS has two exhaust pipes, not the joined box Derby vehicles normally had in this era. Both vehicles carry electrification flashes. Michael Mensing.

E50004; Sheffield, January 1967. E50004 was the first DMU to be painted at Doncaster in rail-blue livery; the double-arrow symbols were painted by hand. BR produced a Design Manual when the double arrow was introduced, and this showed that the double arrow always faced forward when displayed on a ship's funnel. The paintshop at Doncaster mis-interpreted this, thinking that - as with the original BR crest - the arrow should always face the front, and so E50004 emerged from Doncaster incorrectly liveried on the driver's side. I don't know how long this remained before being corrected. David Faircloth.
