Decision day today. After a lot of thought I decided to lengthen the layout by 6″, making it now 5′ overall. This modification allows another point and siding to be added, and three sidings to be lengthened. It will increase the loco isolations from 6 to 11 on the layout. The reason I did this was because if I had not done it I would have always wondered why not!!! I have also got 15 BR(E) Engines!!!
