Re: My first baseboard experiment

If the rusting is bad enough to cause pitting it is likely to give very poor running but if it is only light surface rust it should be usable after cleaning with the track rubber followed by IPA.

Re: Gaugemaster Prodigy Advance 2 - Settings Values

I think the minimum is 0 and the maximum is 255 or 254 for CVs 3 & 4.

What may not be mentioned on the information sheet is that the decoder can be reset to default values by writing a value of 8 to CV 8. This is a fairly standard way of resetting decoders but a few use different values.

Re: Gaugemaster Prodigy Advance 2 - Settings Values

The R8249 decoder is very basic and doesn't support start, top and mid speed settings, see the leaflet that comes with the decoder for the CVs that it does support and the range of values. CV 3 controls acceleration, a small value (default is 5) means it will accelerate quite briskly. A high value m...

Wheel size is measured over the running surfaces, the tyre, not the flanges.

Re: Very odd running behaviour from a new EMU

Possibly poor track joints. The smaller loco taking little current wouldn't cause much of a voltage drop across a poor, high resistance, track joint but the DMU with lights on could.

Re: Dc and dcc

You can usually run a DCC loco with an analogue (dc) controller unless the dc running capability of the decoder has been disabled. You cannot run a dc loco on DCC. Some DCC controllers claim to have the ability to run a dc loco on DCC address 0 (zero) but this is NOT RECOMMENDED as the loco motor ca...

Re: Sound decoder making strange sounds.

...The speaker cables were intact. However I did test the cables & put another speaker on, & the sound was still distorted. Each time the loco movement worked OK. With that information, the next thing I would do is disconnect the speaker wires from the decoder, and connect the decoder sound...

Re: Incline

The steepest recommended gradient is 30 to 1 which means 1 unit of rise (height) for every 30 units of length.

In your case, to rise 8 inches you would need a minimum of 8 x 30 inches, which is 240 inches (20 feet) plus a bit more to allow for the extra drag of the curves.

Re: dcc decoders, used,

They won't display their addresses unless they have Railcom installed and enabled. Your DCC controller must also be Railcom enabled too - most aren't. Just give them a new address if your controller allows it or reset them, when the address should default to 3. PS. It is possible to read various CVs...
