Having the old and new units, aimed at different scales, would be very, very sensible.

Hi Jenny, interesting video. You briefly mentioned that the Hornsby stay alive could be used with other decoders. That’s begs the question - do the HM70000 decoders include the charging circuitry to support purely capacitive stay alive of any value, or do they require the stay alive to include the charging / inrush control circuitry? It would be great if you took a scalpel to the Hornby stay alive to see if the pcb includes any components other than the capacitors…..

A very informative video thanks Jenny. 🚂

I’m a TT modeller. I have fitted several HM 7000 decoder’s. When running the engines stutter around the layout. I installed a power bank the old type. My Welshman Class 43 ran well. But after a while my decoder stopped working and melted the body to my class 43. Don’t know what to do. I did find it incredibly hard to find a suitable place to fit the power bank. I haven’t contacted HORNBY yet as I work away all week. I’m a long distance truck driver.

Excellent news Jenny!
Ps would you mind me sharing a screen shot of the power bank in the A4 tender in the Facebook TT120 groups? (With credit/mention of course)

I have a Pug I need to fit with a powerbank so this size is ideal, it's a horrible runner (even after a full tear down) but because of that, I'd be worried that a small power bank will be depleted quite quickly and then not actually help where as a it might be a better idea for me to shoehorn in a larger bank just so I can be confident any issues are eliminated.

Like others, I really hope Hornby keep the more powerful ones available. Obviously they needed something for TT120, but the very short duration in your test would concern me in a short wheelbase loco over multiple points. I’d rather buy Hornby’s than other brands for my HM7000 decoders, even though the AE ones seem to work well.

We need a miniature one incorporated into a decoder and for a real challenge N gauge, we don't need 5 seconds even 2 would improve things.

That looks great for locos where space is minimal. I do hope they keep the more powerful units in the range though.
Cheers and thanks for the info Jenny.
