Thanks for the comments: seems that persevering with the truckcam will be worth the effort.
Test number two this evening, from the Up line this time. 
Afraid the start is rather rough and ready, then the USB camera rubs against the platform edge going through Churston and the leading bogie is forced through the cross-over onto the down line and the wagon finishes off the circuit spanning both lines.  Not worried about that as I am designing a custom mount that will ensure clearances in the future.  I replaced the light bulb in the man cave today with a new low energy 3150 lumen daylight white item I found loafing in the cupboard. As far as I am concerned that certainly has made a positive difference, but I have an even brighter 3500lm daylight LED item on the way through Amazon, so who knows?
Anyway, here is the video:

That was a good promo text! You got me thinking, this I gotta see!  ;)

Actually, it was quite suspenseful... I spent the entire circuit wondering what would happen when it got back to the guard's van parked on the seawall!  ;D

Lighting definitely better, but maybe could be a tad brighter.  :beers:

I was expecting a crash/de-railing too ;D
I will try a third test video in daylight hours shortly.   
Think I may have mentioned it before, but the length of the mainline, loops, etc around the outside of the man cave (what you see in the videos so far) totals 39.4m/128'. On top of that the branch and fuel depot will add another 11.2m/36' to keep clean when I get to running on those boards. 
Current policy is to use a track rubber where necessary to remove paint/glue, vacuum with a hand-held Dyson and then push the track cleaning wagon around a few times.  There is a controlled drip of cleaning fluid onto the back of the pad which has a slight downward pressure maintained by a spring and limiting screws.  Judging by the colour of the pad, it does a good job keeping the rail tops clean and I'm very happy with the wagon overall.



It all takes time, but the benefit to running reliability is clear (thank you Martin).  The time taken and the general faffage involved is the downside, so I have been looking at ways to make the cleaning/maintenance task easier.
First idea was from a Model Rail magazine item where someone had modified a OO brake van so that glass fibre pen refills cleaned the rails whilst rolling.  I modified a Peco kit by adding 2 aluminium tubes to hold the fibre refills. Obviously in N gauge we don't have so much space to play with, so i had to cut the refills down a lot to fit in the first place: then they were so light that I was concerned that they wouldn't actually do and burnishing.  I reduced the length another 5 mm and made up some M2 screw/nut washer weights to press down inside the tubes. 



I haven't made any measurements, but you can feel the extra resistance when you push the van along by hand so they must be doing the job. I have now added an additional 5g weight to the bottom of the van to help it stay on the rails over the points.



With respect to picking up all the dust and crud that falls on the track, my design flaw of having those long runs behind the back scenes doesn't help when it comes to vacuuming. The increasing amount of line-side scenic detail I am adding is also at risk of being damaged by the tool and then being sucked to be lost forever.  However Google and You Tube helped me to identify this as the answer to my first world model railway problem:



There are many very positive reviews as to it's capability and flexibility. It seemed to be just the job, but could only find availability as new items on e-Bay as an already expensive import from either the USA or Japan with additional high p&p charges plus the prospect of customs duty and the Post Office handling charge.  Last week I found a second hand one come up and managed to "win" it on Friday and it arrived this morning.  It was considerably less than half the price of a new one from abroad and looking at it I would say it has never been used: all the pads present and untouched, no marks anywhere or dust in the fan/collecting box.  I have the DCC conversion to do this evening, but it isn't a difficult job and I have a wired decoder available.

Test video number 3
« Reply #444 on: April 21, 2020, 04:04:05 PM »
Bit longer this time and more for me to note.
I had the train run around a couple times at the low speed to check reliable running: it fooled me!  ::)
0:40 Noticed a few kinks in what I thought was straight track: to be fixed idc.
0:50 2 cable clips had come free and the dropper wire knocked the USB camera - note for later in the clip ;) (They have now been glued back in place)
1:20 2 HSTs in the Trago storage loops Virgin is a 2+7 and GWR a 2+8. 
2:50 Into Churston, no problems with fouling the platform this time with out a fat elastic band on the side
3:10 stalled on the cross over point (see slow speed check comment above!)
3:40 I speeded up to minimise time behind the back scene: error!! :doh:
3:58 knocked the loose dropper again and moved the stick well off centre.  You can see the wagon tilting to the right
4:35 Off centre weight messes up the balance through the diamond crossing and dumps the camera, but does allow an unusual angle on the train departing over the bridge  :wave:

Anyway, daytime plus the new light = acceptable exposure :thumbsup:

The train heading off into the distance is very effective, actually.
As the class 22 and its train can be passed, could anything be filmed coming in the opposite direction to the camera train as that always tends to look good?

I'll change it for next time and see if anyone notices  ;)
Thanks to the instruction sheet NPN.  Next test will be in daytime on the down side again once I have made the camera mount.  I'll have something running on the opposite track as you suggest and use sound fitted locos :thumbsup:
