I've also decided to make a shift in the direction I was taking with the type of signals we are installing on the layout. Originally I had planned to install masts & dwarfs only, but I have now decided to also incorporate signal bridges.
One of the reasons was that they really set the scene, and I do like the challenge of getting something like this built and working. I managed to get some help from a guy in the USA by the name of Marc Samuelson, Marc is a Norfolk Southern engineer and is the signal installer and guru at the Lehigh & Keystone Valley RR (LKVMRR) in Bethlehem, PA.
Marc has installed many of the their signals on signal bridges. One of these is the IHC Signal Bridge kit.
These kits have long been out of production and sometimes they pop up on eBay, Marc and I were actually bidding on one complete kit a little while ago (I won the bidding too) and this is how I learn't that these were perfect for our layout and the area & era.
Luckily enough (shear luck actually) I have sourced enough kits for the entire layout. These are a little different a "Watering Tower" kit by IHC but the exact same molds for the steel structure.
So one section of Harrisburg has four tracks (main, two passing sidings & industry track) converging into one single main. The interlocking past this section has a few crossovers and is all curved. To incorporate the CR1988 - Signal Aspects of Slow Approach & Slow Clear I needed to install triple head masts. I purchased two of the Tomar H-861 Triple Head Searchlight masts for this purpose.
So to begin I have made up the first of the IHC Signal Bridge Kits, and placed it in the area that it will be located.
The next stage will be to upgrade the triple head searchlight to the newer Tri-Coloured LED's and install it onto the signal bridge.
