I was just thinking the same Tony - full of atmosphere AND purpose - a winning combination.
It feels like the Gooey interchange needs a standard gauge 121 DMU or something now for the passenger services!! I would also love to see a more W&L inspired tank engine in use, perhaps bashing one onto an LGB 0-6-0 chassis from the Corpet or Frank S? (or even the Spreewald) using some of the GRS detailing bits? It feels like the W&G would have had it's own engines built, just like the W&L Beyer Peacocks, the L&M Kitsons and the Manning Wardles on the L&B.
