Following on:

As this is the rear loco of the train,it will have the gear towers isolated so it can be dragged. Done by dropping the bogie out, removing the two crosshead screws holding the bogie pivot and lifting out the worm and driveshaft.

It's already fitted with sound and I'm going to retain the sound decoder in it, as recent examples of t'n't passing my house have had the rear loco idling.

I've worked out the decoder settings so I can use the existing decoder in the loco. The ESU Loksound has the capability to alter the auxiliary outputs from constant/blinking (phase 1)/blinking (phase 2)/strobe/double strobe/firebox/mars/gyro/etc.

The blinking and strobe rates are too slow - approx 0.5-0.8Hz, but I discovered that the strobe rate can be altered in multiples of 65.536ms...........

So the alterations to the decoder are:

CV116 = 63 (Auxiliary 2 set to strobe)

CV112 = 10 (Strobe rate of 1.52Hz)

The LED will be wired to aux2 from the decoder and the existing tail-lights disconnected. (66622 has already had the modification to enable switched tail-lights).

I will retain all the parts and wiring should I ever want to reconfigure the loco back to normal.

Quick tip - so I don't lose the driveshafts and worms in case I ever want to re-power the loco, I've taped them to the chassis inside the body!

The camera has picked up a light bleed from the LED - but this is not visible to the naked eye!

Cheers,

Mick
