My rule of thumb - you don’t need a booster until your layout fills both car spots in your double garage. Although that is an OO comment. Using a Hornby controller with their 4 Amp supply will likely run 10-12 trains at the same time and meet your needs without a booster. However, you can future-proof it by wiring it up in 2 districts with separate buses then, in the first instance, wire both districts together to the one controller and see how you go. If you find later you are running out of power, separate the buses and power the second with a booster.

Run a second production process from PCB component stuffing, saving a few cheap components in low quantity, and hope it comes out cheaper overall? Good luck.

Then there should be one wire connected to each pickup strip back to the PCB adjacent to the motor.

See Brew Man’s last - the pickups are not behind the wheels, they contact the back of the driving wheels. There will be wires connected to them going to the PCB mounted adjacent to the motor - see Parts 3 and 4 in the service sheet diagram.

Could this thread please be moved to the HM | DCC forum where it belongs, noting Colin is using a (recommended) DC supply and so no conventional DCC. I would also change the title by deleting DCC and inserting HM7000 for the same reason as moving it. Although I suspect this topic will be short as Steve may well have solved it.

With Hornby and HRMS being separate, and no RM update since release of HM7000 decoders, it is not surprising that they are yet to be listed in RM. hopefully that will be rectified when the overdue major RM update is released. In the meantime, manual entry is going to be the order of the day. Might I suggest (another?) email to George pointing out the latest on your difficulties with this particular decoder and the difference to your others with no problems?

And from this side of the world, the preferred SI units would be 3250 x 1250.

Try turning off DC Running in CV29 and see if it makes a difference.

Otherwise, it’s called Railmaster. Checkout the RM forum below.

What are you using to power your track?

Bee, can only agree with clear comms on here and that on occasion quoting posts helps. My point is mainly about the unnecessary instance of quoting posts immediately above, like this one. And then there are straightforward topics where it is clear if reply is to a post considerably above.

Interesting but unkosher. We are not talking about mains hum here, 50 or 60Hz, we are talking about RF (radio frequency) AM (amplitude modulated) hash, possibly produced by a poor switchmode supply, but more likely by the motor. When TVs were AM, that could be a problem. Now, with FM/digital TVs, not an issue in general.

Agree with RAF you don’t need DCC types but then, in this day and age, you don’t actually need RF suppression either. You could simply connect by soldering a bus wire from the controllers to the rails in each loop.

Just to update Australian supply, my local hobby store has a total of 40 TT:120 items in its catalogue with no new items in something like 12 months. They include the original 2 sets and 6 locos, 5 steam and 1 x 08. Then if Rails can ship 4 Mk3s to me for a total of £18 postage (Hornby charge would have been 4 x £50), why would I go elsewhere.

Would be interesting to know just how prevalent this problem is given it has now been reported in multiple threads along with how to fix for those willing to do a little disassembly.

Another satisfied customer using the standard fix that has been working across multiple threads. And just on deleting and reloading the app - known to be unnecessary. All it achieves is lots of work reloading locos. No big deal when you have only two locos, a pain for nothing if you have 20.

Knob-turn on press has been well-documented. With the zero, before returning, try repeated presses to see if it improves.

All valid. And Rob, post roll-up is exactly why I said handled more elegantly. PS. Note no need to quote Rob’s post to direct a reply to him. In fact, no need to @96RAF to do so.

Paul’s last post was on 5 Feb on the New Platform topic in this forum prior to its release. Although Rob summarised the features to be included as the Mods were already playing with (trialing) it.

On the previous forum, a lot of advice was given to not unnecessarily quote replies, rather use the text box at the bottom of the page and the green reply button. What’s changed? It now seems de rigeur to quote posts in replies, even when the reply is immediately below the post. Although I will admit that it is handled far more elegantly now. Irrespective, I shall continue to not.

Forum history also suggests that a number of running problems are solved by going to 4 Amp, even when apparently not overloading the 1 Amp.

While as RAF says there is a bug being worked on for this, it is most unusual that unlink/remove loco from shed/re-link doesn’t work.

Mine have a little further to travel.

That would have been a very expensive single HM7000 decoder at £90 odd. It is of course 2 discounted decoders. Given we are talking HM7000 decoders, and in addition to Dodge’s photo above, take a look in the HM | DCC forum where there is extensive discussion of the digital HST including its lights.
