#261 Hudson Tunnel Dimensions
Length at base - house side 9 1/2", length other side at base 8 3/4".
Maximum height - base to top of highest peak - 6 1/2"
Base to top of tunnel opening - 4 3/4"
Width of tunnel opening at base - 5 1/2"
Overall width of tunnel - just a shade less than 8".
It just occurred to me that I've never actually run the Clipper set with the tunnel - I just went up and checked. With the engine on O gauge track it is a tight fit - about a half an inch all around with respect to cab roof/fittings and cab roof overhang.
The #26 set is packed away so I'll have to dig it out - I do recall measuring it and I'm almost certain it is the same dimensions as Flyer listed for the No. 82 but I will rummage and get back to you on that.
As long as I'm here - I do have another tunnel to add to the photo gallery. The label is missing but you can see where one was attached on the inside. It matches the #263 Hoosac dimensions and catalog illustration so I've always assumed that is what it was. However, as you can see the paint treatment is quite different from the one you have pictured. Given the differences in the paint treatment of some of the other tunnels you have shown I guess this isn't surprising.
