First tunnel portal

I've had mock-tunnel portals made from cardboard on the layout for quite some time. Today, the first actual portal was installed.

This is a heavily modified Busch 7022 "Dampflok Tunnelportal" I bought by accident a couple years ago. The original is made for steam engines -- no catenary -- so the portal height it is quite low, just over 7 cm. I cut out the original arch stones in the portal opening enlarging it to an inside height of 9 cm. Then I installed a Faller arch stone strip in the new opening. The left side of the portal wall is heavily trimmed for clearance with adjacent scenery. The retaining wall on the left, as well as the tunnel crown, is from the Busch kit, too. Judicious application of Scuptamold will integrate this with the surrounding scenery.
