Bigger and better version of my Western railroad tunnel.
About this creation
I have revamped my Modular Western tunnel by combining it with my father's older stand-alone tunnel design. This design makes the interior walls more realistic, while still preserving the rough rock-work outside.
The modular bit comes in when you disconnect the tunnel into it's three components, 2 identical end-caps and 1 middle section. This is for ease of transport and making the tunnel shorter or longer depending on your needs.
Here is what the inside looks of the tunnel like.
the three sections connect via four Technic pins.
As an added bonus, the flat roof lets you put a small Native American village or a small US Cavalry outpost. If you are not into Wild West models, the tunnel easily recolors with the Dark Tan to dark bluish gray and the regular tan to light bluish gray via the LDD file below. (It's not that hard to recolor it in the program, so only the tan version of the tunnel is included.)
