Description: Single length module with tunnel portal. Part of set with Tunnel Approach to the left. Module is 8.25" deep, and built following directions found on the Building Modules with 1x3s tutorial page.
The tunnel itself is only 2.5in deep, so easy to reach any derailments and clean the track. Back side of tunnel is painted 'sky blue' to make for friendly viewing of the connecting module. Tunnel clearances adhere to NRMA standards. We have had it attached to the tight curve of a T-Junction module (seen in first image), and were running long passenger cars through with no issue. (NOTE: I do not know if double stacks will fit or not at this time)
