When I was a kid, 40-ish years ago, I was an avid model railroader. I built a great 6x8 layout with three main tracks, a switching yard, and three transformer packs. As I grew older and became more interested in computers and technology, my interest waned. I sold my layout, but kept my favorite locos and rolling stock, kept in a box and stored in various closets over the years.
About five years ago, my interest started to re-emerge. I was thrilled to learn about DCC, the exciting technology that was clearly revolutionizing the hobby. But as computers and phones and other devices became wireless, I was surprised to see that DCC remained mostly a hard-wired solution, with the control signals being sent down the track to the locos. I wondered why none of the big players were pushing truly wireless solutions using 802.11 or Bluetooth or Zigbee. I didn’t want to invest in a technology platform that I could tell was reaching its natural end-of-life. So I waited.
When I came across LocoFi about two years ago, I immediately recognized its potential and appeal. I wouldn’t need an expensive hard-wired control system and I could use a smartphone or tablet as the controller. Bingo. I bought in.
Over the past 18 months, I’ve purchased and installed 10 Locofi controllers, both 1st and 2nd generations. I scoured eBay for good deals on quality locos sporting my preferred livery: the Louisville & Nashville railroad that had an active route near my childhood neighborhood. I tweaked and tuned up each loco, carefully installed the Locos controllers, and created custom horn and running sound files for each one. The Locofi development team were a big help, providing valuable guidance on how to make the systems work perfectly I had a blast!
But one thing I didn’t have: an actual layout to run them on! Seriously, for the first year or so I just had the locos on my desk, running on a single piece of flex-track hooked to an old 12 volt laptop power supply. It was fun, but I quickly realized I needed more.
So with the start of the pandemic, I began drawing up plans for a densely-packet 4x8 layout. I gathered advice online for the frame, base, and wiring. I bought RailModeller Pro and spent a month or two tweaking my layout. I ordered everything online and began the build on top of the ping-pong tabletop that sits on top of my billiard table. Here's the final product...
It’s not beautiful, and it won’t be not he cover of Model Railroader anytime soon, but it works great. I used 1/2-inch pink foam insulation board as the base so I could rearrange things easily in the future if desired. No cork roadbed. No signals. No electrified turnouts. Just flex track and Peco turnouts.
I spent a long time planning and building the control board where I can control power to seven different districts including a turntable. The spokes of that turntable are on a reversible circuit so I can rotate locos 180 degrees without shorting out the rest of the layout. Three of the power districts are fed by one 12v power supply; the other four are fed by a different power supply, all wired together on the neutral lead so trains can run easily from one district to the other with no shorts.
I played around with circuit breakers for each district – using either automotive taillight bulbs or the NCE circuit breaker gizmos – but I could never get that working right so I removed it. The Locofi guys had lots of great advice, but apparently my older locos were pulling more amps than the circuits could handle.
I routinely run 6 or more locos simultaneously – though it’s a bit tricky to do without the locos running into each other like that scene from the old Addams Family TV show! The system could definitely handle all 10 locos moving at once though probably not on the same power district because it would pull too many amps. But with an extra set of hands and extra Android device, I could maybe pull it off.
Here's a video I shot of an operating session last week:
The outermost oval has a single Locofi-controlled E7 pulling a few passenger cars. The next oval inward is running a very old SP Daylight 4-8-4 steam loco that is not Locofi controlled – it's just running on that power district at full throttle, LOL. And the third oval in is running an F7 A&B consist. There are 6 other Loco-fi controlled locos idling around the turntable, ready to head out on the tracks when needed. And then a single Locofi-controller switcher loco in the yard. Eventually I'll add Locofi to the steam loco, though that'll require some fancy wiring to the tender car and a revamp of the sound files.
By the way, I had to heavily modify how power is fed to the tracks on that turntable so that it would remain constant while rotating. The stock Walthers design kinda sucks; the locos would power on and off constantly, but with my mods they get constant power and don't need to be rebooted after the turning stops. That was annoying.
Although the Locofi controller app on my Android device does not yet allow you to control a consist with a single throttle (coming soon!), I have run multi-loco consists the old fashioned way: by connecting them together on the track and slowly increasing the throttle speed on each one, quickly switching back and forth between the loco control screens to tweak their speeds, as shown with the F7 A&B units in the video above. I haven’t burned out any loco motors... yet. I’m looking forward to the next version of the controller app – and an iPhone version, both of which are in development.
Like any emerging technology, there are a few hiccups – though I’ll save those very minor issues for a future post. But suffice it to say that I'm a big fan. I haven’t ever run my Locofi-equipped locos on someone else’s layout, but theoretically I should be able to walk up to just about any layout and drop one on the tracks and start running – assuming they let me!
So even if you already have a big investment in hard-wired DCC systems, you should give Locofi a try. It’s a cool technology and it’s definitely the way of the future. Buying a few controllers from them will help fund their development of this great tech – and allow them to expand into battery assist, deadrail, and other potential features. Plus you'll get to play around with something cool and exciting that might just convince you to walk away from that big investment you've made in that NCE or Digitrax system you bought years ago!
And if you're new to the hobby (or recently rejoining it like I am), you should give it a try as well – especially if you like to tinker with things like I do. Enjoy! 😀
Very cool... And I love that Batman print in the background, LOL!
Well, when I started my brothers made fun of me - "you gonna have trees and houses?" and my response was "nah, I just want to run some trains". However, here I am:
Interesting that I found my way to LocoFi for a similar reason. I had my Dad's old DC only stuff (much of it built from kits) and saw DCC as (1) overkill for 4x8 (2) expensive for entry - promised wifey I wasn't going to blow my pension on this (3) being in technology, figured there had to be a better way to control trains - losing all this crazy wiring. My design point was to be able to run two trains at a time. Now my roster has grown into many steam loco's (US and foreign) and I spend a lot of time servicing, repairing and figuring out while trains derail (many in unique locations). So I'm nearing the point of dumping this layout and going all flex track and Peco turnouts (ignored that suggestion from local hobby shop) vs the Atlas stuff. That may draw some raised eyebrows. But if I do that, I would seriously consider skipping all the scenic stuff - never was much of an artist and I'll never have a layout that will be in Model Railroader anyway.
Once again, thanks for sharing this, lots to think about. And for my friends at LocoFI - still would like to see the IOS version of the controller and a steam loco option. I agree it's probably going to need to go into the tender- an interesting wiring issue - a custom cable bundle/ connector may be needed
Thanks for the kind words, Steven. The outer oval is 22" snap track, the inner oval is 18" snap track, and the middle oval is all flex track. I tried to get a consistent 1.75" between each oval, but i had to cheat the joints a bit here and there on the inner and outer ovals to get that spacing. So there are a few gaps at some of the joints here and there, but nothing big enough to affect operations.
I spent a lot of time playing with RailModeller Pro to see how much track I could squeeze onto that 4x8 layout. I came up with some creative uses for those Peco SL-99 three-way turnouts and an SL-99 double-slip turnout and 24-degree crossing as well – which helped me cram a lot on there! Here's the actual layout plan from RailModeller Pro – though nothing ever comes out exactly as you plan it...
Part of the reason I wired each loop as a separate power district (activated by the toggle switches on my control panel and shown in different colors on the plan) was so that I could run my SP Daylight 4-8-4 steam loco on the outer oval with an old DC transformer if I wanted to in the future. I haven't really set that up yet... and it's on my To Do list to get another Locofi decoder and figure out how to wire it. There's not a lot of room in the shell to accommodate a decoder on that very old loco, so I'll probably have to put it in the tender. I'll also have to play around with modifying the diesel loco sound files accordingly, which I've had fun doing with the Audacity sound editing software.
Like you, I'm really just kinda tinkering with the whole thing – not trying to run any prototype operations. But after a long day of work and dealing with the pandemic and all the other craziness in this world, it's pretty soothing to just fire up the layout and run a few trains around in circles for a while! And having the whole layout on foam board without roadbed or ballast means I can change it out whenever I want. In fact, I'm already thinking about some small changes to the layout that will make it easier to move opposing trains on and off the various ovals. That's the fun part for me – planning and building and tweaking!
Really impressive and I'm jealous. My 4x8 is only 3 years old and showing some aches and pains. I'm curious as to the curve radii on the 3 ovals. My 22 and 18" curves are already a challenge and I'm a freelanced "excursion" scene so I can accommodate all my steam loco's (I'm a big fan of steam, but enjoy having some diesels, including my two LocoFi machines, with another in planning). The larger steam loco's can be a challenge on the 18" curves, and rivet-counter types would shame me for the long passenger cars getting around even the 22" curves!
Unfortunately, all that steam means I need to run mixed mode (DC and LocoFI), I can do that, technically, but haven't really run that much. In fact haven't run a lot - being a small layout, I'm doing it for my enjoyment, not really into prototypical operations.
Is this really just 4x8? Seems like you've backed a lot of track (and turntable) into that space. I'm really thinking about torching this layout, salvage whatever flex track I can, tossing the atlas turnouts and laying a new foam board on top of the current hacked-together benchwork. Wifey may kill me... but I like your minimal track prep, as I spent a lot of time laying down road bed and ballasting- which I'll have to undo if I decide to torch this one.😀
Thank you Dave for the supportive and encouraging words. They mean a lot to us!
