I have seen plenty of photos from the BR steam era that generally shows a brake/guards van at both ends of a passenger train and of course on the end of goods trains.
My question is this however. Did a guard ride in the rear coach of a parcel train or at any other point? If not, why is a parcel train not required to have a guard/brake a the end?
What about mixed trains. I have seen photos of short, 1-4 coach length passenger trains with what look like 12 ton vans stuck on the back, no brake/guard at the rear though. How come a 12 ton van in a goods train needs a brake at the end but when attached to a couple of mk 1 etc it does not?
