I am aware that a number of BR mainline diesel locos (which had only vacuum train brakes) were fitted with EQ brakes in the late 1960s.
From memory, I seem to recall that some Class 20s, 24s, 25s, 27s and 40s (and probably other classes) were fitted with these, and had the distinctive Gresham and Craven‘s EQ brake valve on the driver’s desk.
What is the purpose of this modification; was it an experiment? How do these differ from conventional vacuum train brakes? How many locos had it, and what was the reason for certain locos being fitted with them and not others?
I don’t think any locos retained them after they were modified for dual braking, but I could be wrong.
