The Bridge Over Tunnel Runby is a bridge spanning over a tunnel portal. Its exact location is unknown, but it is located somewhere along the Main Line and appears to intersect with Thomas’ Branch Line. Specifically, the Main Line crosses the bridge while the branch line goes through the tunnel.
It first appeared in the nineteenth series and has made infrequent appearances since.
- The exact location of the bridge is unknown, as the geography of the area does not appear to match any landmark on the official map of the Island of Sodor.
