Hello, I am from Chile and I am working on a layout of a station placed on Valparaiso called Puerto. I would like to get help and corrections of my interlocking table to make sure is correct before I construct the interlocking mechanism. To help with the understanding of my project, I link the track diagram and a brief description of the signal functioning on Chilean railway rules. I would really appreciate your answer as a way to learn more about mechanical interlocking and keep the trains alive in some form. Ps: In this station, there are use of economical facing points and for that reason; we have only red and black levers. The text below is the mencioned " Brief description of the signalling of the Puerto terminal station": PUERTO TERMINAL STATION This terminal station has five line platforms, that arrange themselves from 1 to 5, starting from the luggage cellar. The platform lines are connected to tree main lines: Down, Up and Train shed line. Home signals by the down line: The trains that start from “Barón” would find, before entering the “Bellavista” platform, a repeating signal mounted on top of a rigid frame to the left side of the track. This will illuminate clear, only when the next signals are clear too, giving direct route to the train until the interior of the “Puerto” platforms. After that, there is the outer home signal and another inner home signal of bifurcation. The outer home signal is on the left side of the track, coming from behind the “Bellavista” platforms. Is simple and when it indicates clear, it authorize the train to proceed for another 150 meters until the next inner home signal, placed to the left side of the track. The inner home signal of bifurcation is double and it has a route indicator, which points at, the platform line that will receive the train with a shining number. Under this shining number, there are two signals: in the top there is a main signal and under a shunting signal. With the main signal clear and the shunting signal at danger, the train is authorize to enter the platform witch number is shown in the indicator, with the reassurance that the platform it is free of trains. With the main signal at danger and the shunting signal clear, the train is authorize to enter only with caution to the platform witch number is shown in the indicator because the platform could be in use by another train or a blockage. With one of the two signal clear, and the indicator turn off, the train should proceed ready to stop in case of an obstacle before the entry to the platforms. Start signal from shed to line 3: The start to the sidings from the shed to “Puerto”, going form line 3, it is authorize by a simple signal place close to the level crossing of “Edwards” street. Home signal by line 3: The home to the “Puerto” platforms for a train dispatch from the shed by line 3, it is authorize by the bifurcation signal place to the left side of the first point of “Puerto”. This sign works the same as the bifurcation signal of the down line. Start signals: There are two main outer start signals place a bit before the start of the “Bellavista” platforms: One for the up line that when cleared it is authorized to proceed until “Barón”, and another by line 3 that when cleared it is authorized to proceed until the point placed on “Edwards” street. There is also double inner start signals, place at the end of the “Puerto” platforms that authorize the exit from any of the platforms. When the upper signal shows clear, the train can proceed until the outer start signal of the up line or the shed line. The below signal authorize shunting. The platform line 1 and 2 have a common inner start signal, but in the interior of each line there is a dwarf shunting signal that indicates witch of them can proceed. Shunting: A lever placed at the end of platforms, which is usually locked, moves the crossovers in the interior of platforms. To proceed with movements in the crossover an authorization is required by outside phone in contact to the signal box. thank you!
