There are three lead, two color LEDs available and you bias each lead as necessary. You can use two diodes in series (one reversed), with the bi-color LED and also series an appropriate resistor to di

Gentlemen, The only place a short should occur is at a reverse loop or at a "Y. It doesn't matter if the polarities are reversed or not because your reverser, your PM42, or separate booster will make

Inside the pit there is a circle of track. It consists of two almost semi-circles with two small insulated sections, the size of the bridge, opposite each other, in an unused area. Each semi is powere

I may be giving away my age but once upon a time, to jumper a rail joint, a jumper was soldered from rail to rail avoiding the rail joiner. The rail joiner could be soldered but that would condemn the

Don, do you have a drawing for that, I am presently using one relay per Tortoise Motor and a diode matrix. jd

Brett, First, you can look up old articles of Model Railroader on line. There are some amazing articles on all sorts of wiring and they have the staff to make very understandable drawings. Wiring for

Switch machines are not high current so almost any rotary switch should work. It does need to be Brake before make so it doesn't activate two switches at once. If more than one turnout is going to ope

Twist Again, that is rich. Here is the deal, if you run wires in parallel what ever is on one will to some degree cross over. It is exactly the way a transformer works. If it is just AC or DC there is

It could be track! I have found a number of Rail Joiners that just don't make good contact. Although rare, it has happened. I have also discovered a number of cold solder joint connections on tracks.

You didn't mention what kind of reverser you are using so your help will be general. The input to the reverser is your non-isolated track and the output to the reversing section. Your instructions tel

Check something on your switches, preferably a spare because in place won't work. Use a volt ohm meter or a continuity tester and see if the two rails at the frog are connected. If they are at least o

Just two cents but: Any time you run a pair of wires in parallel with a voltage on them, they are more likely to affect other conductors, be affected by other conductors, and increase in capacitance.

Sounds a little odd. If your districts are isolated by DB150s then only one district should respond. Districts need to be isolated so that a derail doesn't take out the entire layout. Our club, CrossR

Here is another option for shutting down. Wire your track through a Digitrax PM42 or a similar device. You would be able to wire up to 4 tracks or 4 blocks with it. If you still want a buzzer, wire a

Max, I think you are going to start another conversation. Use Ruby Fluid applied with a brush (To conserve). Blue fluid is also highly recommended especially for PC Boards. Ruby fluid works great on N

Hello, I worked for the "Phone Company" for many years and for AT&T for many more. The connectors you are talking of are excellent but they have some problems. There are a number of different connecto

Thank you, You answered my worst fear, that the 240 needs it own power supply. You also fixed the problem by sending me to a much less expensive supply. We solved our problem, at least for the near fu

We are presently using a Digitrax 200 command station and a Digitrax 150 as a booster. Our portable layout uses a Digitrax 150 as a command station.

Has anyone had a chance to research the new Digitrax 240. My club is presently powering our layout with control station, 8 amp, 200 and a 5 amp booster running off a substantial 16 volt AC transformer
