Wandles Trains Posted September 10, 2012 Share Posted September 10, 2012 Hi guys i was wondering if it is possible to make one of my hornby triang trains in to dcc. I know that you can make more modern non dcc ready trains into dcc but was wondering if it was posible to make a hornby triang train into dcc. If you can help please reply Thanks for help Matthew Link to comment Share on other sites More sharing options...
The_Seagull Posted September 10, 2012 Share Posted September 10, 2012 Hi Mathew.....i cant answer your query, but those on here who will be able to help, will probably need a little more to go on, things like catalogue number and type/name of the train you want to update...best of luck...

Wandles Trains Posted September 10, 2012 Author Share Posted September 10, 2012 the train is a class 3f tank locomotive. Link to comment Share on other sites More sharing options...
Rog RJ Posted September 10, 2012 Share Posted September 10, 2012 Virtually any loco can be converted to DCC. Some are easy and some are a bit more difficult. Link to comment Share on other sites More sharing options...
Wandles Trains Posted September 11, 2012 Author Share Posted September 11, 2012 ok thanks i was just wondering because it only has 1 pickup wire Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 11, 2012 Share Posted September 11, 2012 Hi WT, from a quick search, I'm assuming your loco looks something like that in http://www.hornbyguide.com/service_sheet_details.asp?sheetid=46 If so, conversion is simple. The reason you have only one pickup wire is the other side pickup is via the chassis, hence the connector and soldered wire under the screw holding the motor to the chassis. Waht you need to do is remove all connections from the brushes (including removing that little clip around the one brush) and the wire connected at the screw holding the motor to the chassis. Also remove and discard the capacitor across the brushes. The spring holding the brushes in place is insulated on one side. You can cut that insulation in half and use the other half to insulate the other brush so neither touches the spring holding them in place. Now connect decoder red to the one pickup wire and decoder black to the connector at the screw holding the motor to the chassis. Then connect/solder decoder orange to one brush and decoder grey to the other. Put on the track and test. One thing though - the Hornby R8249 may not have sufficient power for this motor, depending on its condition and the magnetic field strength in the magnet. You should use a higher output decoder like the Sapphire or another brand. Link to comment Share on other sites More sharing options...

Fishmanoz Posted September 12, 2012 Share Posted September 12, 2012 Yes, ypou can buy one of the neomagnets assuming it is an X04 (didn't check the part number with the one I looked up) but I'd stiill use a higher output decoder, not the 8249. You can do a stall current test though to prove it one way or the other if you wish. Link to comment Share on other sites More sharing options...
Wandles Trains Posted September 12, 2012 Author Share Posted September 12, 2012 ok thanks what wires would you use for the smoke generator Link to comment Share on other sites More sharing options...
poliss Posted September 12, 2012 Share Posted September 12, 2012 You would connect it to the function wires of the decoder. Link to comment Share on other sites More sharing options...
Gregd99 Posted September 13, 2012 Share Posted September 13, 2012 do check the current drawn by a smoke unit before connecting it. some (most? all?) decoders function outputs are limited to 100mA. Link to comment Share on other sites More sharing options...

poliss Posted September 13, 2012 Share Posted September 13, 2012 Problem easily solved. Use the purple and green function wires. Attach both of those wires to one side, and the blue wire to the other side. You'll need to remap both function wires to the same button of course, and make sure both functions are set to turn on to constant brightness in both directions to avoid a directional smoke unit.

Flashbang Posted September 13, 2012 Share Posted September 13, 2012 How do you re map the function outputs on the R8249? Link to comment Share on other sites More sharing options...
Flashbang Posted September 13, 2012 Share Posted September 13, 2012 Darn that posted itself!!! I was going to add... Alternatively use a micro 12 volt relay. Connectthe relays coil to green or the Purple/violet wire (Function F3 or F4) and Blue, then via the relays contact switch the smoke unit On/Off. The power to feed the smoke unit via the relays contact coming from the DCC powered rails (Red and Black decoder wire connections). Link to comment Share on other sites More sharing options...
poliss Posted September 13, 2012 Share Posted September 13, 2012 Would you use an R8249 on an older loco? I'd use a more powerful decoder which allowed function remapping. Link to comment Share on other sites More sharing options...
Wandles Trains Posted September 17, 2012 Author Share Posted September 17, 2012 so does the sapphire have wires on it that i can solder Link to comment Share on other sites More sharing options...
Fishmanoz Posted September 17, 2012 Share Posted September 17, 2012 Yes it does, just like the 8249. Link to comment Share on other sites More sharing options...
