Thanks g.venkatesan, but One Could Expect a Very Small Amount of Heat Dissipation.
Thanks .*., as I Suspected.
Thanks Very Much Retired EE.

Can I connect multiple HO scale model train power pack controllers together to run multiple engines at once?

Answer by Old Man Dirt
If they are going to be in a single block and operated as unit, it is better just to buy a bigger power pack. If you want to run them as separate trains, then you need to either wire in blocks for the trains to operate and have separate power packs or go with command controls.

Question by Jerod: Does anybody have any advice on how to quickly perform power chords on electric guitar?
Like switch from an E to Dm with very little to no pause between? Like how can I train my fingers to do so quickly?

It takes patience and practice. The best tip I could give you is to learn all of your scales and chords and just practice. Pretty soon changing chords gets easier. Good luck =)

what type of resistor do i need for 19 and 15 volt power supply?

Question by darpo1: what type of resistor do i need for 19 and 15 volt power supply?
I am connecting regular standard bulbs ( for model railroading) that are 12 volts (25-30 M-amps), however my power supply has 15 volts for DC and 19 for AC. Im going to connect them in parrallel using about 6 bulbs into a terminal block. ………..what size resisitor do i need? and should i connect only one resisitor for all 6 bulbs or each circuit should have its own .

thanks

Answer by Garth W
The easiest way to handle this is to use two silicon diodes rated for at least 1 amp and have a 1.5 volt drop each that will drop your 15 volts to 12 volts. I would full wave rectify the ac output and use 2-3 more diodes to drop the voltage further. I would not use a power resistor to divide the voltage.

Running two model trains on one track with one power pack?

Wednesday, August 15th, 2012

Question by Yoshiko: Running two model trains on one track with one power pack?
I’m just beginning to explore the hobby of model railroading, and I currently have an HO train running on a simple oval. I think I’d like to purchase a new HO engine, and I was wondering if it would work if I ran it on my current track at the same time as my other engine. Can one power pack handle both trains at once? I read that it may be possible, but the trains will operate at different speeds and will eventually crash into each other. Would it be better for me to build a whole new track just for the new engine and purchase a second power supply?

Also, do you recommend that a beginner should read Model Railroader magazine? I want to expand my knowledge of model railroading, but I’m not sure if the magazine only focuses on advanced audiences.

Best answer:

Answer by Angry Sailor 302
The magazine “Model Railroader” is mainly geared towards intermediate to advanced modelers.

It is possible to control two trains on one loop of track with one power pack.

You could set up the track in “blocks” where you can shut off power (or with a variable resistor, throttle the power), where the trains can be independently controlled.

Adding sidings is another method, where you can shift one train to a siding to allow the other to pass.

There are a lot of methods out there, limited only by your budget and what you are capable of doing.

It would be better to have a second loop, perhaps connected with turnouts to run two trains. My layout has two loops with a small yard, allowing three locomotives to run at once.
