I worked on the railway station at Huddersfield for a few years, starting from spring 1979. I seem to remember C&D was collection and delivery.
We had many thousands of C&D parcels up until 1981, when BR withdrew themselves from the service, allegedly due to it being loss making !
The fleet of "National carriers" trucks, used to go to Grattan (one of the mail order catalogue firms) in Bradford and Shaw carpets at Darton (Barnsley) among others, to collect loads and bring them in to us at Huddersfield station, although the carpets normally went to Clayton West in time to meet up with the lunch time DMU service and we had to load them into BRUTE's, then later in the day, they went on an early evening train, consisting of around four parcel vans, hauled by a class 31 locomotive, to Wakefield Kirkgate. I guess they were formed into a longer train(s) at Kirkgate, as many of the parcels were bound for London, Wales and Scotland.
Red Star was an express service, where parcels were brought in to us by the customer and their items went on sheduled passenger services under the watchful eye of the guard. One chap brought us a television set, wrapped in a plastic dustbin bag and expected to send it "Red star" to London for him, but we sent him away to package it more securely and we never saw him again ! However many local firms sent machine parts and valves by "Red star" on a regular basis, without problem. Most items went on direct trains, or only had one change en route to their destination.
Another, slower service was "To be called for" TBCF, where people could send less urgent items by passenger train and more changes were allowed on those items, but without the guaranteed arrival time that "Red star" offered.
