Try removing the body from a Bachmann EMU to install a decoder. Took longer to get the body off and repair the damage to the underframe detail than it did for the decoder to arrive by post and fit it....... oh, and the cuts to my thumbs I wont even mention. Oh, I just did.

Funny you say that the Bachmann 416 took me weeks to do as the back lugs just wouldn’t lift...... I didn’t want to force it so left it and eventually got it off and could see exactly where the lugs were....luckily I had the replacement bodies Bachmann had sent out due due to the numbers issue but still the instructions didn’t help with the issue at all

Going back a little, and drifting just a little off-topic, I think it is high time Hornby dropped the 8-pin socket altogether ... and don't get me started on that ridiculous 4-pin version they came out with.

Bachmann got smart a long time ago, using the same PCBs for their models regardless of whether or not they had sound fitted. Most of the diesels and electrics got 21-pin interfaces, and if one wanted to change to sound, all one had to do was fit the sound decoder and solder the speaker(s) to the marked solder pads on the PCB. For smaller locos, they have moved from 6-pin to NEXT18. They now are moving to PLuX22 for newer models.
 

Hornby have now switched small locos (0-6-0ST Pecketts, Ruston diesels, and Stephenson's Rocket to name a few) to 6-pin, but their compulsion to keep the 8-pin for larger locos is puzzling. They did use 21-pin for the earlier sound locos with ESU decoders, but even those were not standard as the LED wiring was different to the standard non-sound models.

To get up to date and even ahead of the market, they really need to move to PLuX22 for larger locos, and NEXT18 for smaller locos, standardise PCBs with provision for sound (pads for speakers to be easily added - surely there would be economies of scale in using only one PCBdesign for any given model), and, of course, leave room for the decoders and speakers to be fitted. Come on Hornby, how about it? The class 71 shows a lack of forward thinking, but we do know you can do it if you try.

Yes. However, Hornby doesn’t try. When an engineering sample arrives, someone should try to fit a decoder and a speaker to see if it’s possible. Someone should also try to fit the extra bits to make sure that they do fit and should check that flanged trailing wheels can be fitted to Pacifics. I have some Hornby Pacifics where that could be done, then what does Hornby do? There’s a solid chunk of chassis preventing the fitting of flanged trailing wheels to the Merchant Navies and the A2/2s. That sort of cock up is worthy of Bulleid and Thompson themselves.

I think the 8 pin option on steam locomotives has more to do with the lack of functions need by the chip and I guess may change once more lights and effects etc are incorporated in to new models
