For years people have told me that they have seen "tanks" on British railways. What they probably mean is the Warrior, which has got tracks, with a turret, and with a gun. But it has only got a small gun that can not knock out any heavy armour such as tanks, and has relatively thin armour compared with a tank. And so I decided to make a railway diorama with my Challenger tank. This would have to be either Germany or Poland, or in Canada, which is what I've chosen here. This is a photo of a scene based on the rail movement of British Army military vehicles to and from the British Army Training Unit Suffield (BATUS) in Alberta, Canada. I understand that this happens about half a dozen times a year.
