SReturning to railway modeling

Hello,

First time posting to the forum, i'll try not to sound stupid (definitely will though).

 

First off, i'm in America.  I plan to be running Hornby trains and would like to do it in DCC.  I'll be using a Bachmann 44932 E-Z Command (unless someone really has had a bad experiance with it) on a mix of different brand code 100 HO track.  I plan to use a Hornby R8206 power track.  There is a clip on the end of the wire that comes with the Bachmann 44932 that plugs into the track, can i just remove that and put the wires directly into the connectors on the R8206?  Please tell me if any of this sounds wrong.

 

My first train is going to be a Hornby Intercity 125 R401.  How dificult would it be to update it to DCC? 

 

Please let me know if you have any questions.

 

Thanks,

Matt

Hi

Welcome to the Forum.

You should not use the R8206 power track as supplied on a DCC powered layout. It has a capacitor fitted inside that will alter badly the DCC signal causing poor running.  Ideally obtain the Hornby R8241 Digital power track section. Alternatively you can flip open the cover on the R8206 and snip out the capacitor found inside and discard it.

You can of course then insert the two wires from the Bachmann DCC controller. The wires can go in either way around it doesn't matter which way they are fitted.

 

Please remember that the Bachmann EZ Command DCC system is a very basic one and cannot have more than 9 DCC locos in the address range 1 to 9. It cannot read CV or write them (except alter address numbers which is technically CV1). It cannot operate any accessories by DCC either.  But it will work and allow Hornby locos that are DCC Fitted to work. DCC Sounds will not all be available either.

Broken? It wasn't me. I never touched it!

Sorry I was timed out, so Im starting a new second reply.. 

The Hornby HST R401 is not DCC Ready, so it will need the DCC decoder hard wired to the motor. This will involve serious testing and checks to ensure the motor is totally isolated from the rails/wheels before a decoder is fitted. Failure to ensure this will result in immediate decoder failure when placed on DCC powered rails!  There are several web sites that will explain the conversion process, but unfortunately its not a simple plug and play option.

I personally would look for a DCC Fitted loco or train then reconsider your options around the R401.

Modifying the R602 and/or R8206 and/or the R8201 for DCC compatibility.

Thank you both for your input!  i'll try to find a DCC ready Intercity...

Since i have not purchased the power track piece yet, i will just buy the R8241.  Is that the only piece i need to make the track DCC compatible?  All the other track can be normal stock, right?

 

Regading accessories, i wanted to do powered switches.  I assume i cannot connect them to the Bachmann system?  So i would need seperate power for those?  I'm really not looking for anything too complex, so the sounds and more than 9 locos are definitely no big deal for me, also the layout will be 4'x8' so pretty small.

 

And thanks for the newbie tip Chris, much appreciated!

 

Thanks again for all your help!

Is that the only piece I need to make the track DCC compatible?

 

If its Hornby track and going to be DCC controlled through a single connection from the controller, then the Hornby points will need R8232 DCC point clips in order to circumvent the electrically isolating nature of Hornby points and make all extremes of the layout track live at all times. The R8232 DCC point clips are not needed if you implement a DCC power BUS with droppers based DCC power distribution system. But note that a BUS based power distribution system is going to be difficult to achieve without resorting to soldering wires to rails.

 

 

If you are going to use traditional non DCC control of the points, then I would recommend either a 16 Volt AC transformer source, or a 19 Volts DC ex Laptop power supply and feed the appropriate output of one of those into a CDU [Capacitor Discharge Unit]. The output of the CDU will provide more than enough power to operate the most stubborn Solenoid point motors.

 

The operating switches used with a CDU need to be a single pole change-over that are non-locking and sprung biased to a centre-off position. Alternatively, the PECO PL-26 switches are compatible for use with a CDU. Whereas the Hornby R044 point operating switches are not 100% compatible.

 

The ex Laptop 19 volt DC supply will be an easier and probably cheaper purchase than a 16 volts AC cased transformer.

Hey Matt, Flashbang is being really modest about various sites available with info on DCC conversions.  One of the better ones is his very own. Google Brian Lambert to find it.

 

And on your intended controller, that sounds very, very basic from what Flashbang says.  Why don't you consider Hornby's basic offering in the Select. You need to buy it new and ensure it has either v1.6 or v2 firmware (they are the same except the latter comes in a newer face-lifted box).  You could buy cheaper second hand but almost certainly that will have older firmware, nowhere near as good and needing return to UK for upgrade.   The Select will address up to 60 locos and can also control points. It can also changes CVs, which may not seem important now but, sooner or later, you'll wish you could. 

and thanks for all the fish

Hi

Let me first say I am a enthusiast, not a modeller as are many on this forum are, but as your in the states if your going to look at a new controller may I suggest a Digitrax DCS52 (price is comparable to Hornby) It does everything you will ever need to do (change adresses, read/write CV's, control points etc.) with the added bonus of being expandable if needed, as well as adding extra throttles without the need of a new controller. (I use a second hand Hornby R8250 as a second throttle).Also if your using different branded 100 HO track you might think to use the Peco PL 80 Rail joiners eqidistant on your track to ensure smooth running rather than soldering wires to your track, the more experienced modellers here will say that there is a downside to using them, which may be true, but as yet I have had no problem with them, plus my soldering skills are rubbish.
