Steam, diesel, electric, heavy rail, light rail. If it has run on rails between 1825 and 2024 I'm interested. As my late friend Steve Sykes so aptly put it, "show me a side track and I'm off down it"!
Model in 2mm Finescale but appreciate good modelling in any scale.
Well strictly speaking, all electro-diesels are bi-mode, but not all bi-modes are necessarily electro-diesel. So it leaves the door open for novel technologies, like Roger Ford's bionic duckweed.
