The Rutherford West - Interlocking Signal Bridge is the boundary between Hershey & Rutherford. The aspects shown below are "Medium Clear" (left mast) & "Approach Medium" (right mast).
The signal bridge protects the North bound mains to both Harrisburg & Carlisle Junction, it also protects the yard lead into Rutherford Yard - South.
The Harrisburg main is protected by the triple head mast on the left. The triple head signal mast allows for a "Slow Clear" aspect as the main can be diverted into the south bound passing siding through the Harrisburg Industrial area.
The Carlisle Junction main and the Rutherford Yard - South Yard Lead are protected by the double head signal mast on the right. There is no requirement for a triple head on this side as I do not need a slow clear, the main aspect into the Yard Lead will be a "Restricting" aspect.
The process to add the G-Type heads using the IHC plastic kits has been fairly easy and quick to install. The small 1.5mm butterfly/axial LED's go together quite quickly too. The colours on the green & yellow are not as good as the RR CirKits's but they are much better than Tomar ones.
Next step is to install a pair of G-Type standalone masts on the westbound end of Hershey, and a double head dwarf protecting the crossover from Hershey into Rutherford (to the left of the last photo).
