Back2Bay6 is about a half hour's drive from Stafford. I drove over there myself when my son was at the University there at Beaconside.

Steve is a great bloke and very helpful....

I have both types on the MR.
The resin type via eBay are quite brittle, and they curve quite tightly inward at the bottom.
It was while trimming these curves that I found they were brittle.
The cain Howley type is far better. He also does interior extensions.
Pic shows my very tall 16mm Baldrig in the C.H. entrance.

As a matter of interest are there any double track tunnel entrances made?
I can't recall seeing any.

The best building tip is always to look at the real thing first. The photo of the arch under construction tells the whole story, showing how the blocks fit and work together, and how a well proportioned arch ought to look. You can see how each block is carefully dressed to transmit the load efficiently to the adjacent blocks. You will sometimes see rubble masonry fill, but the arch stones still have to be fitted if they are to work properly. A lot of models, even commercial ones, couldn't stand up on their own if they weren't one-piece castings! Some of the best designs are still those of the Roman engineers, who could build an arch that didn't need mortar to cement the stones together, and would stand for a couple of thousand years. Many of the stone railway bridges and tunnels of the nineteenth century are their direct descendants, without many changes at all.

Incidentally, a useful liner for garden railway tunnels is the clay chimney liner that you can find at builder's merchants. The square type works very nicely.
