Mount it. Plug it in. Run trains.
Layout control without the proprietary price tag — built for you, shipped to you.
Most layout electronics end up as a pile of boards screwed under the benchwork, wired a little at a time, documented nowhere. I build it the other way: one Digital Dispatcher or cabinet, everything on DIN rail, every wire loomed and labeled, tested as a system before it leaves my shop. When it arrives, your job is connecting your layout to it — not building it.
A complete DCC-EX + DEJA.js installation, ready to plug in to your layout.
Runs on DEJA.js (free): throttles, turnouts, signals, sensors, and routes from any phone or tablet. Try the live demo (opens in a new tab)
Not included: your track, turnouts, and layout-side wiring.
Fixed price, fixed parts. Need something different? That's what a custom build is for. Build your own
Point at a part to find it in the drawing.
Fixed price, fixed parts, built and tested before it ships. Pick the one that fits what you already have.
The RTR without the power supply, for a layout that already has one.
A command station plus an Arduino Mega with every port on terminals, and a PWM driver. Sized for a shelf layout; you bring the computer.
Everything in the Shelf, plus a second Arduino Mega for more I/O and a WLED controller for layout lighting. You bring the computer.
One of every device I build with, in one enclosure: every kind of turnout, signals, detection, relays and lighting. You bring the computer.
DCC-EX on an Arduino Mega and Motor Shield, on a plate in a small open frame. The simplest way I build it.
More turnouts for a layout that already runs DEJA: servo control on an Arduino Mega, by USB to your DEJA Server.
Inputs and outputs anywhere on the layout, on WiFi to your DEJA Server.
Separate, fused power for logic, accessories and track, with a live meter so you can see what the layout draws.
One more power district: an EX-CSB1 in booster mode, wired and labeled, fed from your command station.
Several Digital Dispatchers planned and built as one system for your layout. Every one is custom, so we start with a call.
A command station, USB and WiFi nodes out on the layout, lighting, and clean power: the same architecture as my own railroad.
What's in it
Every device type, more nodes, and three power districts, run from members' phones and tablets.
What's in it
A Digital Dispatcher is the hardware. DEJA.js is the software that runs it. Here's what goes inside, how you run it, and how it gets to your layout.
I build all of your layout's wiring needs into one easily installable unit. You mount it, plug it in, and run. Form follows the job — it might be a cabinet, a DIN-rail build, or boards mounted on plexiglass with standoffs.
It mounts on the front of your layout — not underneath.
Everything is right in front of you, so anything that ever needs attention is easy to reach and easy to debug. No crawling under the benchwork.
Underneath, there's almost nothing to do.
Your devices connect to the wiring harness the Digital Dispatcher provides — labeled, snap-in connectors.
Take it, install it, plug it in.
The complexity happened in my shop; the install is deliberately simple.
DEJA.js is the software I wrote to run my own railroad, and it's free. DCC-EX puts DCC on your rails; DEJA.js is how you run your railroad from any device. Anyone can install it — and I'm here to help if you want it.
Throttle — the app
One web app for your roster, throttles, turnouts, signals, sensors, automations, and routes. It runs on any phone, tablet, or computer at throttle.dejajs.com.
DEJA Server — on your layout
Runs on your layout and connects the app to your DCC-EX command station and the devices on your railroad.
In the Digital Dispatcher RTR, the DEJA Server runs on the included Raspberry Pi. See the RTR
Try the live demo (opens in a new tab)Plus the control panels below. Every build is scoped from your layout; this list is what I can build around.
Control panels: mix these however you operate.
The free DEJA app on any phone, tablet, or computer. This is the control panel most people use, and it's already built.
Try the live demo (opens in a new tab)A mounted touchscreen at your yard, staging, or dispatcher position, running DEJA full-time. I build and configure it as part of your system.
Custom-built to your track plan: labeled switches for turnouts and accessories, laid out the way your railroad actually runs.
Scales & compatibility: N, HO, O. Works with your existing DCC-EX setup or starts fresh.
My part
Free discovery call first (15 min): we spec your Digital Dispatcher for your layout, then you get a plan and a fixed written quote. No surprises later.
I build, wire, configure, and test it in my shop. You get photo updates as it comes together.
It ships to you labeled, with a wiring diagram.
Your part
You mount the enclosure on the front of your layout.
Land your track bus and accessories on the labeled harness — premium snap-in connectors, no soldering.
Power up and run trains. If you get stuck, a troubleshooting session is one booking away.
Pick what your layout needs in six plain-English steps and watch your Digital Dispatcher come together as you go. Then take the summary to your free call.
Example: Medium Layout
Extruded aluminum enclosures, customizable per build — drawers, coverings, plexiglass or solid panels, DIN rail inside to support all of your electronic mounting needs.
Every Digital Dispatcher is designed from your layout — track plan, districts, turnout count, signals, accessories. The discovery call starts that process.
15 minutes, no obligation, nothing to prepare. You'll get a fixed written quote.
