I'm just ranting
I bought DS the Tesco Mountain Railway set for his birthday. It has a mountain with a tunnel through it, lots of track, trees, farm animals and 2 trains. It looks great it really does and it fits his masses of wooden railway sets
But
2 points
One of the trains is too big to go through the tunnel. I've spent ages rebuilding the layout but, it's not me, the train is too tall
and
The second layout suggestion just cannot be done with the pieces provided. The bridge piece you put across the mountain is too wide to fit into the narrow gap I'm supposed to put it in.
OK, it's a small thing and DS has lots of other bits I can substitute to make it work but, what If DS wasn't a serial wooden train addict. If this was the only set you had, the design failings could be very disappointing.
OK, rant over, will invest in BRIO in future.
