DCC Hybrid

With the DCC hybrid method you can use a small DCC decoder that will only source an amp or two and use it to power your lights and sounds, then use a large ESC to drive the motors. Often, for smaller locomotives and railcars, a 2 amp DCC decoder will handle everything but if you want to avoid the cost and need something bigger, this may be an option. Generally if you are purchasing all the parts at once, it’s…

Battery Sources

I use 14.8v 4S (4S = 4 cells) Lipo batteries in my main locomotives but if you are planning on big locos and long trains you might want to consider 18.5v packs. It depends as they say. Unlike Nicads or Nmh batteries, Lipo cells are 3.7 volts each so 4 gives you 14.8 volts. In smaller things like critters or rail cars I use 2 or 3 cell packs. I order packs from Hobby King. I like their ‘lipo finder’…

Battery DCC

If you are not very familiar with DCC, here is a quick explaination. DCC stands for Digital Command Control and is a standard implemented and maintained by the National Model Railroad Association (NMRA). It is a unique form of control that got it’s start in the smaller scales. A digital control waveform is ‘superimposed’ on the DC power signal that goes out on the rails. This waveform is actually a series of digital messages, repeated over and over. Each of…

Overview

Blueridge Engineering makes boards and kits to drive Large Scale Model Trains using Battery Power and DCC decoders. We also offer solutions for Live Steam locomotives using Servo controls. We support three main controller types, the Protothrottle, the Airwire T5000 controller and Android Phones (via bluetooth). Using these controllers we have three different types of receiver units – a standard receiver that can accept Xbee (protothrottle), BlueTooth (android control) and 915Mhz (Airwire) Network boards. We also offer an Airwire Receiver…

Power Connections

Power Connections For most of my battery powered road and switch locomotives I use a 14.8v 4 cell lipo battery pack. For the smaller critters and railcars and such, I use a 3 cell or smaller pack at 11.1v or less. A good source of these is Hobby King They have a method on their page to search for a particular battery by dimensions so you can measure the inside of your loco and then find a battery pack to…

Battery Power

Battery Power without using DCC requires the use of an ESC- Electronic Speed Control. ESCs take a servo input and turn it into motor voltage. There are ESCs for ‘brushless’ motors and ‘brushed’ motors. All Large Scale Trains, to my knowledge, use brushed motors. There are two types of ESC operation. The first is the servo throw goes full left for full stop and full right for full speed. A power relay is used to switch the polarity to the…
