Morning all,
For me, part of the appeal was the thought that the S&D brought Midland/LM&SR motive power through Somerset/Dorset with some L&SWR/Southern ( and later, BR standards) with the permanent way and buildings being the responsibility of the L&SWR/Southern, hence the colours. Add in various Midland/LMS locos hauling L&SWR/Southern stock, Midland/ LNWR and LMS coaches and it's arguably unique character signs through..........all right in the heart of GWR territory. No wonder they were miffed.
How it all came about is a fascinating insight into the business end of the pre-grouping scene.
