Three wagons, a loco and caboose. Very pretty.
I know "pretty" isn't supposed to be in the vocabulary of a "serious" railway modeller, but outside, I quite like it. Colourful trains running through a colourful garden setting works for me.
The HLW wagons fit nicely with the plasticy Oho and caboose from LGB's "Toy Train" range. I think a longer train is called for. There is a flatbed in the collection, but I've lost the axles for this in storage, but when the order I placed for replacements turns up, I'll finish it off.
Toy Trains have one big advantage in the garden. They make great track testers. If Oho, or his brother Otto, fall off due to stray ballast or track in need of fettling, they seem to survive. I'd rather risk then than a pricey Accucraft Isle of Man loco!
