Converting older locos to DCC
Thanks.
And of course, the next question -- Will I screw it up playing with it on a DC track?
I would really like to just start out building this with DCC, but I have some old locomotives that are not DCC ready and that I doubt are going to be easily converted, if they can be converted at all.
I have a couple of old Life-Like E8s in Mopac Eagle livery, and they have been in the closet for a long, long time. And I have a set of Eagle passenger cars to go with them. These are the driving inspiration for building a layout because my father worked for Mopac, and we rode Mopac passenger trains all over the Midwest back in the 50s and 60s. so I want those Mopac Eagles on my layout regardless of whatever else is on there.
So I can't do the layout without them. (Yes, it's an obsession. I've been wanting to build this for 25 years and I am finally going to do so.)
Which brings us to next question -- Can older locomotives like these be converted to DCC? And if so, how difficult is it? Do I need to go back to college and get an electrical engineering degree to pull it off? Are there places to hire it done?
All of my other motive power is DCC ready -- Kato F3s and a Kato E5 are DCC ready, so I should be able to drop in the converter and go. It's just the Mopac E8s that are approaching antique status.
Thoughts? Can you help give me an excuse to get that DCC controller you referred to?

Yes, and yes. :laugh:
Yes, you could screw it up by operating it on DC. I would definitely NOT continue to run that DCC equipped locomotive on DC, at least not as it is. Newer locomotives are often factory-equipped with "dual mode decoders", designed to work on either DC or DCC. However there is a CV (configuration value) that must be changed for it to operate on DC. (correctly and without the possibility of damage to/smoke from, the decoder.) Catch 22, to change any CV, you need access to a DCC system. So there's your excuse to buy an NCE Powercab DCC controller. It sells for about $200, you may find discounts too.
www.modeltrainstuff.com is a good online dealer.
Yes, you can hire someone to install a DCC decoder for you. First you have to find somebody in your area that does it, and then you have to pay them to do it.
Yes, in most cases you can convert an older DC locomotive to DCC. To do that you need to disconnect the motor from the frame electrically, and wire in a DCC decoder. It's not hard to do as long as you can read the directions that come with the decoder, and are reasonably competent at soldering small wires to small terminals, on small circuit boards. Key word small.

There is an excellent book available on the subject. It's called "Basic DCC Wiring" by Mike Polsgrove. You can order a copy from

Having worked as an electronics service technician for 40-some years, and having seen what electronic engineers can do to mess up a machine, I wouldn't recommend going to the trouble of getting the college degree! :smilie_daumenneg:
Some really old locomotives are not worth converting. I go back in N-scale to the 1970s. Back then N-scale locos had crude, three-pole, motors, no flywheels, and two speeds, Too fast, and stop. If you have any of those antiques, I wouldn't bother.
The other problem with some old DC locomotives is that the plastic bodies were completely filled, and I mean wall-to-wall, and floor-to-ceiling, with metal mechanism/weight. This does not leave any room for the decoder. There are ways around this. You can have the mechanism machined ("milled") to make room for a decoder. There are companies that do this for a fee. You can do the same thing yourself, but there are problems to watch out for. Before you take your trusty hacksaw, and file, to your locomotive, you should mark the cut lines on the frame. Then completely disassemble the loco and save all the parts in a covered container or Ziploc bag. Then you can cut/file the frame without getting metal bits into the motor, the gears, and other places where they shouldn't be. Sounds like loads of fun doesn't it? :smilie_auslachen:
I don't think so either. There is a saner method. You can mount the decoder in a dummy diesel unit, or the tender of a steam locomotive. This will mean connecting four small wires from the trailing dummy unit up to the powered locomotive. Two wires are from the wheel contacts into the decoder, and the other pair carry the power from the decoder to the motor up front. Add another pair for a headlight if you want that to work. Not ideal, but easier than being your own machine shop.
Your Life Like eagle E-8 units probably have room in them. those are pretty big locomotives.
Finally there is a way to convert your Eagle to DCC without any work, but it costs money. Kato makes beautiful super smooth running E-8 locomotives. I have several, and they're great. Mine are DC but these days, you can probably buy a Kato E-8 factory-equipped with DCC and sound. If your Life Like shell will fit over the Kato mechanism, you can just swap shells. If not, you would need to repaint the kato unit in Eagle colors. In either case, I suggest looking for an undecorated Kato E-8. That will work for the shell swap, and if you need to paint, you won't need to strip the Union Pacific, Santa Fe, whatever, paint off The Kato shell first.
DCC adds so much finer control, the possibility of sound, and lots less wiring than DC. I should think that would be all the "excuse" you would need!
Have fun;
