My hubby collects n gauge and oo gauge model trains and has set up a layout to play with them. He knows that this is an 044 side tank M7, southern railway engine…. just from looking at a photo. He said its an old fashioned steam engine that was introduced in about 1964. I find it fascinating that steam engines are still being used across the world. Maybe they will be used for decades to come? His layout is basically an oval with a siding. When it’s set up I will add a photo. The layout had been stored with cobwebs and possibly a spider or two for the last few years, but we’ve decided to release it into the wild (of the garden shed). It is about to become friends with the hedgehogs and the stray cat. I hope it survives.
