The club is also in the throes of developing another large layout the public will be able to enjoy after completion, and future shows are also likely to feature train sets able to be controlled by a cell-phone or personal computer via Wi-Fi.
"Some are equipped with sound and they're all digital command control. The old system if you put two trains on a track, they move forwards or back. The new models have a digital chip inside the loco that picks up the power from the track, and you can control them independently. You don't run the track, you run the train."
Mr Murray said the club layout now being constructed would be digital and had the capacity to have six trains operating simultaneously at the command of half a dozen operators.
"Most of the layouts this weekend will be digital and the Meccano set-up is excellent. It's well worth seeing and will be the first time that layout will be seen in Wairarapa. We have the favourite layouts, including the kids' favourites, and layouts that are different and new as well."
The WBS Model Train Show runs from 10am to 4pm and costs $7 for adults, $3 for children and $15 for families.
