I never got to work at court St. and I was only at the museum for an award ceremony. I worked out of 207 St Yard in a construction gang. Worked on the A, B, C, D, 1, 2, 3, 4, 5, and 6 lines in the Bronx and upper Manhattan. I retired in 1999. I don't model the subway but I have a couple of sets of the redbirds.
The security bar is there because it is in the transit museum, and is an exhibit open to people to come in and look. There is nobody there to keep an eye on things. I guess, now that you mention it, that this must have predated the museum, since it was a somewhat unsecure location.

Here there be cats. LIONS with CAMERAS
Court St. was a bad location. notice the security bar and lock across the levers.
BroadwayLion How do you know that the lever colors are not correct? Well, yes, the signal levers *are* red, but they are supposed to be the outtermost levers, but when I biult the machine all levers controlled switches. When I added signals to the machine, the number 1 and 2 levers were interlocked for the 242nd Street crossover, and lever 3 was not interlocked with anything, so that was used for a signal. I will rewire the levers as part of this renovation project so the Dyckman signal will be the number 1 lever. LION uses simple dogs to interlock adjacent levers, but there is no matrix that interlocks the entire machine. Here is the innards of the machine.

retsignalmtrI was a Signal Maintainer for 31 years. It's your project.
Cool enough! Above (below?) is the machine at Court Street. I *was* under the impression that there was a larger machine at this location (Perhaps in the '70s when I was on an ERA tour) Maybe that was my imagination.
Also incorrect on my machine is the round US&S type lights as opposed to the correct GRS lights. I figured round holes were easier to cut. Here is LION in wood shop with a real NYCT GRS lever. I guess I could have made a mold and cast real levers, (we do have a foundry in the garage building) but the LION is both lazy and cheap, so him made them of wood.
I was a Signal Maintainer for 31 years. It's your project. You can select anything you wish to do on it. Just pointing out what the prototype uses since you are being very detail oriented.
For interlocking machine of LION
Signals = red
Revenue (main line) Turnouts = green
Non-revenue turnouts = yellow
Nice Interlocking machine. Your colors on the levers is a little off. The NYCTA uses Red for signals, Black for Switches, Blue for traffic direction, Yellow are spare levers and White levers are Master levers to lock the machine so nobody can operate it without knowing the right combination of lever position to release the master lever. The TA is eliminating the Electro mechanical interlockings and is already using CBTC (computor based train control) on the IRT. Excelent work.
Wow!
Very nice work Lion.
I use very similar stuff for my signaling, turnout control, and cab selection system which provides CTC, full interlocking protection, ATC and more.
It worked for 75 years on the real railroads, I think it is just fine for our models.

Here is Motherboard of the Route of the Broadway LION. 50 Bits of RAM, the I/O bus is along the top, the 1/60th Hz CPU is not shown. This controls automation of Subway Layout of LION.
Here is Network Card of LION
Here is ouput port (Parallel Output) to stations on this part of the layout.
Here is "Keyboard" (hehehe) Of LION
No Mouse. Is No Mouse. LION eat mouse. All Gone.
It is taking a lot of time to do this wiring project, there are 48 station platform edges each gets five conductors from the "Motherboard -- these control the signals for this section, there is a circuit to detect the passing of a train, and another to lock out the starting clock if the next station is still occupied.
