Tunnel dimensions

Recommended Posts

I'm looking for the dimensions of these type of squared double-track tunnels:

Does someone have a technical drawing or knows where to find one?

The loading gauge and track center could be an alternative.

I’d measure the tunnel in the photo and the train height or width (whose dimensions should be easily found) and estimate it from there.

Socimi,

Scaling from your photo, using the track width at the left (yes, I know it's curved, but it will do as a marker), I make the tunnel width 8.06m (26 1/2 feet) and height 5.3m (!7 1/2 feet).

Didn't do the rail height, but this could be say 200mm (8 inches)

These dimensions probably correct to +/- 100mm.

Regards, 

Bill, 

Melbourne.

Socimi,

If you divide the full size dimensions that I worked out by 150, you get 35.5mm for the height and 53.7mm for the width in N scale, which you're probably wanting.
