Re: American Rebuild

Ah, ok. Not sure how you would reduce the howling ... maybe keep the same open sq inches but relocate it - I assume this plate does not seal up against the water legs .. maybe reduce that gap and drill holes between burners to equal to the area you eliminated (assuming the current open area is worki...

Re: American Rebuild

I can't think of a coating for the inside of the manifold that would stand up to the heat exposure. Slight rust shouldn't be a problem as the gas velocity is very low and even if some comes off it won't get carried far. Looks like your burner is a bit high - in my mind you want the bottom of the fla...

Re: Track Circuit Occupancy Detection

I sell "Profile Insulators" that are CNC cut in West Coast rail profile ($9 per dozen). These are placed between the ends of the rail and held in place by the plastic joint bars. These prevent the rails from coming into contact due to heat/vibration, etc. I plan on offering injection-molded "Joint B...

Re: Capture/Release type circuit?

One thing you have to deal with using "capture & release" systems: Typically when someone captures a block the signal either comes on (red only systems) or it goes from red to green, etc. The point is, unlike automatic systems, the signal is the same after the train enters as it is to permit the tra...

Re: The Viability of Solid-State Components for Signal Systems

I'm assuming it uses those timed relays I was looking at earlier for my signal system? In my search, some different ones came up that were activated by a momentary switch, with an adjustable time until it switched off from seconds to hours, or de-activated by yet another momentary switch. The dead-...

Re: The Viability of Solid-State Components for Signal Systems

Hence we do not have block occupancy detection within turnouts. The adjustable delay-on-clear function in the block occupancy detector attached to a block that includes a turnout is used to "mask" the detection gap. As noted by Chuck, if a short train goes very slowly through such a turnout, or sto...

Re: The Viability of Solid-State Components for Signal Systems

In our ABS, older BODs operate with a 5 volt (nominal) track circuit; newer BODs operate at 3 volts nominal. A track circuit is deemed to be satisfactory if the return voltage is 4.5 or higher in a 5 volt track circuit, or 2.7 or higher in a 3 volt circuit. I reliably detect trains down to 1 volt (...

Re: The Viability of Solid-State Components for Signal Systems

Thanks for the track info, Chuck! EVERY rail joint must be bonded (or insulated), and EVERY turnout must be insulated/bonded? Wow! That's a LOT of work for converting an existing track… Especially for the Lone Wolf track owners. Looks like a Capture/Release system would be easier to install and les...

Re: The Viability of Solid-State Components for Signal Systems

Chuck, why break the block in the middle of the turnout? I was under the impression that the turnout should be included in the "main line" and the isolators placed such that when the train on either route was clear of the fouling point the signal system would show clear. The purpose of the diagram ...

Re: The Viability of Solid-State Components for Signal Systems

Chuck, could you explain a little more on the track requirements for an automated system please. I read about track bonds - how and where? Insulated joints - how? Teflon sheets between fishplates and rail? What about the bolts holding it together shorting out the bond? How about turnout frogs? Just...

Re: Signaling Beyond Simple Passing Sidings

Above are the two block occupancy detectors produced by BCS Technology Limited for riding scale railroads—these items have been available since 2006. From time too time I'm told that my approach to signals is overly complex and that it can be done much simpler. For "Train Separation" (i.e.: uni-dir...
