We visited Miniature World this Sunday.
There were four main layouts (with another very large 00 to be built), a UK one in 00, a European (German/Swiss) in HO, a Japanese one in N, and the G scale one with mainly Piko products.
All looked like typical shop displays, as if they were straight out of the box, rather than a highly detailed exhibition layout. But they were all good never the less, and if it encourages people into the hobby then it's a good thing IMO.
The G scale layout had a couple of end to end shuttles and a couple of circuits, and the track although screwed to boards, had typical garden centre gravel. The grass of course was artificial (as were the bunny rabbits) since the railway is indoors, but as an example to show what could be done, and encourage others into the hobby, then it was fine. It was good fun.
We also visited Merrivale Model Village in Great Yarmouth over the weekend.
Again, we found it to be good fun and we enjoyed looking around. The layout uses mainly LGB track and trains, with a few of the newer items being Piko. It is a large twin track oval and has 4 trains running, 2 on each circuit that are switched alternatively at the station, using LGB track components and point motors. The gardens and plants were being maintained by a dedicated team of 3 gardeners (even on the Sunday and during heavy showers), and the blooms really set off the whole scene.
Cost for both venues was about £7-8 each, and refreshments seemed to be reasonably priced. We both enjoyed the shows.
I would recommend a visit to either if you are holidaying in the area, but think of it as entertainment, rather than serious modelling....
