is it possible to have a bimodal loco conversion, so that it can run independently on track and battery power?
Bimodal loco conversion
- Thread starter Neil Holiday
- Start date
Yes..
At its' most simple, a DPDT switch connects EITHER the track pickups, OR the battery supply, into the rest of the electronics in the loco.
There was an article in the US Model Railway Magazine that just showed such a conversion in HO, but the teck involved is not readily available in the UK so Phils option mentoned above is the best we can do so far. I did list it all some time back in one of the Battery Forums, just don't ask me to find it now!
Building the Multi-Power Loco.... - G Scale Central
and
Multi-Power Loco Mark II.... this time it's steam..... - G Scale Central
These were both built using the Tam Valley Depot DRS receiver and a Stanton radio cab, but now that the Revo DCC system is on the market that may well be a better bet due to its increased range - fitting one is pretty much the same process as I used with the Tam system though.

Yep easy to do, just choose the loco carefully as squeezing in the battery and wiring can be a challenge,
I have a lgb USA shorty loco with a battery and manual speed controller in the tender, and a dpdt switch in the loco to choose track or battery power

My recent Aristo and Fosworks DCC Battery Forums show the setup used to Test out both systems. The DPDT to change between Battery and Track is located in an old Film Canister in the pics.
What is the reasoning behind doing that?
If you have insulated the wheels and remove any pickups then you should be able to just run on battery regardless of what potential is across the rails.
I am at a loss as to why this is done is there a logical explanation that I am missing?
Well, in my case the reasoning was simple - I wanted to have a battery loco that I could take to run when visiting lines that had dead rails, but also to retain the ability to run it on track powered DCC (or DC for that matter) at home, or visiting lines that had track power. While I removed the skates from both converted locos, I left all the wheel pickups in place, they are simply connected through the DPDT track/battery selector switch.
Sometimes I simply want to be able to drive the locos on my regular Massoth DCC control system rather than having to use a separate radio handset.
Jon.
With my testing rigs I wanted to be able to check out the Sounds on Track and then switch to Battery Only to compare Functions. It convinced me that I will leave the option of Track Pickups for pretty well the same reason that Jon has. But it also allows access to reprogramming of the Chip if required, though this can be done via the Aristo DCC Battery Kit it cannot be with the Fosworks Battery kit. Though being used to Massoth reprogramming (well some of it anyway) it made sense to leave this option rather than faffing to learn a new system. Not enough Ram in me bonce you see!
But certainly more expensive, without going down the Battery/Track powered discussion again I think it logical to provide for both if that is ones wish.I think it's easier to have two locos
PEDANTIC MODE OFF
HUMOUR MODE BACK ON

I realise that was (mostly?) a joke, hence the emojis..... but being serious, it was a case of the difference being one DPDT switch that cost about 60p.... so why NOT have the option of either power source?
As JonD said, the track/battery debate is getting about as contentious and polarising as politics and religion, so let's keep off it if we can.
I don't know, maybe using both on one loco labels me a "heretic" to the True Believers on BOTH sides of the argument......?
Jon.
Yes, slightly facetious, but I'm not into the argument - I do both, track and battery - to suit my mood

Absolutely! There is room in the hobby for all methods of propelling your locos (and indeed several combinations of such, as we've been discussing here), depending on personal preference, circumstances and needs.... and long may it stay like that!

I converted a Bachmann TTT engine to switchable battery power, using Peter Spoerer's radio control and sound, with a jack-socket for onboard charging of the batteries - so all granny has to do is put it on charge after use. I also fitted a Seuthe smoke unit with a toggle switch in the cab to turn it off when the smoke oil has run out. My reason was mainly so that my granddaughters can use the railway while I am overseas working, without the risk of damage to my DCC controller, shock, etc. When I am home it is a simple flick of 2 toggle switches underneath and it's ready for DCC operation (yes, l fitted a decoder as well!)
I also did the conversion because . . . . I wanted to! It was a good wintertime project.
I would post pics of the conversion, but I am away again in the coal mine in Utah, and pics are on my pc back home.

tri mode, battery, DC track, DCC .... and a flashing led marquee announcing the mode for all to see....
Had to think about that one for a minute, Greg - I do know what you mean by a marquee (and we do use it as such), but on this side of the pond the word is more commonly used to mean a big tent..... 
Joking aside, my two conversions ARE actually tri-mode - because when switched to track power they will happily run on either DC or DCC....

I think I still had in mind one of the earlier comments about availability of space in a loco for all of the R/C gizzmos - some (locos) have got it, some ain't. But then again, there are trailer (wagon) options so, as you say it depends on personal preference, circumstances and needs...
At the moment, I'm an either / or man, but that's through accident rather than planning - I'm coming round to the way of thinking that if a loco won't behave itself on track power, then it gets the battery conversion - even without going the Li-po or Li-on route, modern battery packs can deliver four hours of playtime
Now, having said that, we have to go back to an earlier topic about track cleaning, and we need to remember that I am on the most troublesome end of the spectrum (for track cleanliness) being DC and skate-free. My big locos with sprung drivers and tender pick-ups are fine over less than perfick track, but my 10-wheeler (based on an Annie chassis) and my Rogers require perfectly clean track, and so suffer from dew at dusk syndrome - therefore battery plans are being formulated
What about quad mode........
DC, DCC, Battery and....... live steam (both coal and gas fired of course) .....
facetious... moi?..........
But to be fair... I run all four but not on the same loco but I do have two locos that are DC,DCC and Batt.
