Switch tower Tunnel entrance


Construction of a tunnel portal :


I do not want the end of my layout to end just against the wall, so I 'm trying to let it end in a small tunnel. The dimensions are 40 cm of length and the same depth as the other segments, 80 cm. The method of construction  I describe here is only the one I use and is cetainly far from perfect and can be improved.

First , I make a drawing of the opening, based on the standard (NEM 105) described at  www.miba.de/morop/  . Since this is a double track , the drawing has to be modified.
A wooden board serves as a support for the plaster molds. The different parts are put together with white joint filler. The large bricks are carved out of clay.  The clay is applied to the wooden board by using white glue When the clay is set, it is painted with Revell steingrau acrylic paint. Some joints are accentuated with a solution of black paint and purified petrol. Its better to apply small quantities  of paint and look for the result after each application.

The inside of the tunnel in not ready  and will be made of the same plaster molds. The tunnel entrance should be a 'black hole'. I'm not shure this wille be so since it's a double track and the opening is relatively large.
