I've always run other peoples S7 locos on my exhibition layouts (Brokenborough, Braunstone Gate, The Field, Y Cae, Aberbeeg and The Back End) but only when time permits and when it works to the correct operating system (such as DCC now). I can appreciate why Love Lane want to keep to the script when showing their railway; we were much the same with Aberbeeg but did allow Richard Carr's 31 to appear in deepest Cymru!
Nearly all the times something comes off it is because of a biological failure; the phrase 'biological failure' originated from the Williams F1 team when a Brumie drove for them!
