Yes, Sundown & Sprawling was an inspiration for me as well - Someone who scratchbuilt Diesel locos when few RTR examples were available - I'm also truly flattered that my old Layout, Fisher Street - Victoria Bridge has been mentioned on these pages!
So what has inspired me over the years then? - Well No.3 for me was IRON MOULD LANE, by the Bristol East MRC. This inspired my exhibition layout 'Rhydwyn Fawr Steel' - No.2 was City Road LT, a London Underground layout by Tim Stevens - Finally No.1 for me was the LONDON, BRISTOL, & SOUTH WALES RAILWAY by John Jay (RM Aug 69, Sep 70, Jul 73). A 4mm scale Early BR(WR) railway with a four-track mainline section - A wonderful concept, with such prototypical features as Sonning and High Wycombe Cuttings, Severn Tunnel (English Portal) modelled, with other locations being brought to mind such as Paddington, Kensal Green, Reading, Bristol (Old Brunelian Terminus), Patchway, Cardiff, Fishguard, and Landore MPD being represented - I would really like to know if any further articles on this layout were ever published!
