Hi Duncan ....
Now that I am retired I have time to launch into long held desire to develop an N-Gauge layout based on the S&DJR :-)))
Problem is that I am getting VERY confused with the types of coaching stock that would have been used on the line between 1948 and it's closure :-((( Your list looks to be very comprehensive and I am very pleased that I have found your posting.
Are you able to tell me if you know if any of the coaching stock, that you have listed in your posting , are available in N-Gauge .... either current or discontinued???
Any suggestions would be very much appreciated.
Regards MIke
