Most of my locos are 2 rail Hornby Dublo with some later Hornby. In fact it was my intention to collect at least one of each of Hornby Dublo locos and rolling stock.
I never caught the DCC bug but I do appreciate that the sound makes a great difference to operating a layout.
I am now retired and do not have loads of money to spend now, but I have considered buying some Lenz loco decoders but as I understand it the basic loco decoder does not produce sound, but control only. Hornby appear to sell the TTS sound decoders for various locos, but my HD locos draw 600 – 750ma even after remagnetising -too much for the Hornby TTS. I take it I would have to purchase these as well and piggy back them to the control decoder? If so does it have to be a Hornby control decoder or can the TSS sound be fitted with any other decoder.
I have also seen some American model rail forums where sound decoders are available to operate off the original 2 rail DC controlled layout - this may be my preferred route – are there any UK suppliers of DC (analogue) sound decoders?
