Re: Signal Complexity

Another question for the professionals.... In my neighborhood (Augusta, Ga) I have seen several mainline CSXT signal heads that have 4 lights; Green Amber Blue and Red. The lunar is used few and far between but when it is, it is used to indicate a main line switch (with throw detector) to an indust...

Re: Signal Complexity

To expand a little on BDD's explanation, an Absolute signal is generally at a location (a Control Point, or OS) where there are remote controlled switches. They would include crossovers and junctions. The 'Absolute' part means that you Absolutely cannot pass a red signal until you have specific auth...

Re: Signal Complexity

On the big ones. the 'fail' position is to red. The block is powered from the 'leaving' end, and as long as there is a circuit, the green/yellow signal relay is 'picked up'. As soon as anything interrupts the circuit, equipment occupying the block, a broken rail, or a Trainmaster with his 'shunt', t...

Re: Signal Complexity

Well, my next question to the pro crews is: If sectioning is scheduling thing (1 logical train, but broken up into 1 or more physical trains), Does dispatch routinely allow more than one train in between the head blocks? I mean, what would be the point? All you would end up doing is stacking up and...

Re: Signal Complexity

BDD is correct. When I hired out, the BN Alliance Division in the PRB was in the process of converting from 'Dark", i.e. Train Order Operation, to CTC. At first, there were no 'Permissive' Intermediate signals, the automatic signals between the controlled 'OS' signals. It wasn't too long before the ...

Re: Signal Complexity

How does a automatic signal system handle multiple train sections within a block? If I understand you question correctly, the first train 'drops' the entering signal to Stop. Any following trains then 'Stop and Proceed' at the Red signal into the block behind it. On the 'Big Railroad', you Proceed ...

Re: Signal Complexity

That's how it happens. The guy on double track didn't stop for the red. I worried about stuff like that, particularly after the Company started using the 'cruise control', aka 'Trip Optimizer'. I never used it, I wasn't about to let a computer run my train. The cruise control isn't PTC, it just know...

Re: Signal Complexity

Standard three-aspect signaling (clear, approach, stop) would work well at EPRR. A lunar will confuse those who have not had full-sized railroad experience. As a former signal maintainer, I revel in complexity. However, most people who are in this hobby are interested in running trains, not studyin...

Re: Erskine Tramway

I've been hauling down and re-splitting firewood to a better size for our 'Finnish Heater'. I've got a trainload stored in the Engine Shed, and today, I parked another two loaded bulkhead cars in there. Even if it snows a lot, I can plow the 'pad' between the house and garage so that I can haul dry ...

I use a program called 'Scale Print' for stuff like this. You plug in a dimension, and it will print it to any scale you need. $20. http://raildriver.com/products/cycloped ... .print.php

Re: British Rail 0-6-0 Class 4 Shunter drawings

Glenn,

I've asked on a British forum. I'll get back to you.
