Good question. The sensors do not measure the length of a train, they only know when a train enters or leaves a block at either of two ends. If a train uncouples, the sensors will not be aware of this and will show the block as clear when the head end of the train exits the block. This is a...

A new circuit enables simpler installation of operating block signals. Traditionally, block signaling required insulated rail joints, resistor wheel sets and current sensing detectors to make the signals work. The Azatrax TS2 is a new product that uses two infrared (IR) sensors to detect trains...

Greetings greggma, Yes, the transformer has two voltage outputs that both use 'COM' as their common return. 'Track' is a variable AC voltage, 'Accy' is a fixed AC voltage typically around 16v. The Accy transformer output is connected to one side of the relay coil (through a rectifier bridge...

This module will control either twin-coil or Tortoise switch machines, using two buttons, and has connections for LED indicators: http://www.azatrax.com/dual-train-detector.html It also can automatically throw the switch when a train approaches, which may be a bonus or it may be overkill for...

As shown, if your train is longer than the loop, the head end will bump the tail end at the switch. As for the short gaps, the idea will work as long as there are no lighted cars or pusher locomotives at the rear. You still have to set proper polarity when the locomotive crosses the gap...

Azatrax has released a new dual channel infrared train detector: http://www.azatrax.com/dual-train-detector.html The model MRD2 detector senses trains at two locations and has two relay contact outputs. User selectable operating modes enable the detector to trigger two different circuits...

Reid, By "normal Atlas switch" I think you're referring to their slide switches where you slide the plastic button to the left or right, then press it to actuate the turnout coil. Personally, I like these because they give a visual indication of how the turnout is set... assuming you did push...

Hammer53, I've modified Lionel's wiring diagram to show what I think you're looking for. Their diagram shows how to wire their gates to the Lionel IR detectors. I've taken out the IR detectors, and now the relay will come on when a train is in the isolated block. I'm not 100% sure how Lionel...

For headlights, I personally use clear LEDs. They're focused like the real thing, so they are much brighter when you're looking at them head on. If your LED shines through some clear plastic in the headlight, more of the light will get to the clear plastic, and the plastic lens will do some...

Hello Hammer53, Do you know the model number of the Lionel gates? I found a few different ones at http://www.lionel.com/Products/ProductFinder/ and entered 'crossing gate' in the search box. Do you have a wiring diagram that came with the gates? It looks like you can download product...
