In 1970s I started collecting stock for my imagined S & D remained open.
I had a Hymech (Hornby) with Mark 1 passenger stock, I had a class 124 trans pennine (Trix) for through trains. I had a pair of Hornby Dublo class 20s for frieght and 08 for shunting. I Intended to use a Park Royal rail car for the branch and would have run Class 20 with 2 coach trains also on the branch.
I did have the Hornby rail car set , which I intended to be used for Bath to Templecombe. I also had the Hornby Pullman set
I sold all of them in the mid 1970s along with all but 2 steam engines when trying to raise as much money as I could for a deposit on a house.
If it had continued, I would have had a Class 33 and mark 2 coaches running from Bournemouth and would have had Class 201-7 DEMU and would definitely had class 47.
