They did... and it did... it's a
runner!!
Earlier in the day Mr. O and me had a bit of fun manoeuvring the beast out of the house and down onto the line. While he took advantage of the glorious spring sunshine to do a bit of tidying preparations in the garden, I made the first drawbar... in between essential, and copious cups of tea of course!

Surprisingly, still well ahead of schedule, the carriage was coupled (at one end) for the initial test:
After I had completed a couple of satisfactory round trips running light, Mr. O fancied being the first passenger... so away we went.
It was just as well that there was plenty of time before the "visitation", as the journey only lasted about three or four seconds! With several violent jerks, the loco decided to become a complete failure!
Multi-meter tests revealed that there was a full twelve volts running from the battery to the control unit... but nowt coming out at any other point. Thank goodness I had decided many moons ago to order a spare... although changing them over proved to be a rather fraught, under the bonnet exercise. First time around, I had connected the controller up and then fed the wires through various apertures. Reversing that procedure was deemed impractical time wise, but in retrospect it might have been the wiser move?!
Mr. O's fingers are much nimbler that mine these days... so it is entirely thanks to his assistance that the task was successfully accomplished!
Happily, the revitalised engine then proved to be quite capable of hauling one adult, (plus driver) but it does require a bit of practiced technique to avoid slippage or stalling on the two sections where the gradient is at the extreme - on the loop after taking the right hand junction, and at the top of the climb up to the driveway. Everywhere else, including when starting on the level, there seems to be more than adequate reserve of power and traction available.
Whilst that was a relief, my main concerns were how stable the carriage would be when moving under load... and perhaps particularly how the suspension would behave for all passengers, large or small during entry and egress! I need not have worried though; as to my utter amazement I found that I could step in and stand with my feet anywhere in the footwell, lean forward to grab a seat back or armrest, and rotate to lower myself into a seat! (Getting up again was no more of an issue than I am familiar with nowadays anyway!) The carriage does roll very slightly, but it is not in the least bit unnerving... and there is clearly no indication of bottoming - or that any of the wheels are even reaching the point of lifting off the rails.
I can still barely believe how smooth and comfortable the ride is too!
In all the excitement I forgot to take enough still photographs... but collectively, we did get some video footage, so I'm hoping that Mr. O or Glenn can sort out the means of putting some footage on here for later?!
Pete.
