@PRRMiddleDivision posted:This week, I have some images of a tunnel lining I built for Spruce Creek Tunnel. The tunnel is curved, and the outside of the curve abuts the aisleway. In order to obtain access to the tunnel, I built two curved walls that can be opened like cabinet doors.
The first image shows the wall framing for one of the two doors adjacent to the tracks. A small caster supports the near end of the door, keeps it in position vertically, and allows it to be pulled out of place while resting on the benchwork. The opposite wall is fixed in place:
This picture shows both of the doors slightly open. These doors allow easy access to the tunnel in case of a derailment and to clean the track:
Excellent planning and execution, Neal!Your personal record has been awarded ten merits for proper planning to prevent poor performance.
