may be pushing it to think that I could use the J94.
Chris,
On this track plan I think you would be unlucky with the J94 due to the overhang front and back....Pugs and Rustons (and even Mannings) fine. One of these 'Inglenook' shunting set-ups might better suit the J94

which is more than can be said of plywood the price of which is listed as 'P.O.A.' in the Wickes catalogue due to a World shortage.
