DCC decoder help

[Ashley-1272867]

I recently bought the hornby Hogwarts express train set and now want to add a decoder to my engine. I also want to add sound to my train. I believe I'm right there because the loco is the DCC ready model with the eight pin slot. but I need to know what decoder I need and is there enough room for a speaker to get the railsounds, bells, whistle ect. Much help would be appreciated.

When I'm unsure of what decoder to install, I have a word with the chaps at digitrains, at least I get good advice then.

Apologies if I am 'preaching to the converted' but you will also need to purchase a DCC controller. Although the loco is DCC-ready, the controller in the set is DC-only.

[P-Henny]

If G.S' assessment is spot on and you haven't yet got a DCC controller. Then when (if) you do get one you will also have to replace or modify the train set track power connector for a DCC Digital version. The DC track power connectors included in sets have capacitors in them that corrupt the DCC Digital track signal. For digital, the track power connector capacitors need removing.

Modification - simply flip open the little black box between the rails on the power track and snip off at its 2 legs the capacitor found in side, then close the box again.

If you go back to DC, it will still work without the capacitor.

If I recall correctly you need Hornby R7294 Decoder which is suitable for Hornby Hall Class, also If I am correct, Hogwarts castle loco is based on the Hall Class Loco.

Yes, based on the Hall. I fitted a non-sound R8249 a few days ago. There is a metal frame in the tender that looks as if it is designed to support a TTS speaker and if I can find an R7294 for sale I might give it a try. The tender is easy enough to open up, although it needed a bit more care to get the body sitting flush on re-assembly.

Edit: the R7294 looks to be out-of-stock everywhere. Used the only option unless you buy a more expensive sound decoder?
