Network Rail thanks (in the embedded video) passengers and freight uses for their patience. No mention of the impatient boater.

I went to see the bridge keeper a few years back. Best job in the world, according to him. Anyway, he said the the boats had the right of way. He derived some enjoyment from annoying his railway bosses by not delaying the opening until when they would have liked.

You're doing yourself a disservice. 30 litres for 10 miles is 1.5mpg.

Also in the 1970s, sometimes a crew member would stand on the counterbalance, which sped things up.

Is not the element of your quote supporting your view of bona fide that of Nigel Moore - who was never a member of the judiciary?

You're not quoting the judge for the greater part

If it is 9kw - and you can make the exchange 100% efficient (unlikely) and the rise in temperature is 40c (not much), you'll only get about 2 litres per minute. A typical pump is more like 10 litres per minute, open flow. All assuming I have worked it out correctly.

Indeed. But if there's not enough water leaking past the top gate to hold the bottom gate, you have to question the merits of closing the gate to save water through leakage.

The Worcs & Birmingham was the exception to most canals as boats kept left when meeting another. It's mentioned by Rolt and the Idle Woman. Maybe the "keep right" sign was thought prudent when the change was made?

House painters prefer a well used brush to a new one. Not only is there less bristle loss, but it is said to be better to use. Is it the same for the professional boat painter?

The 9V was stated in the very first post - so it was clearly a result from the past rather than a reading following the recent suggestions. It was ambiguous as to whether it was with or without the glow plugs connected - but any confusion is down to those making assumptions without checking. If (as originally stated) the problem is invariably a function of whether or not the glowplugs are connected, the current being drawn by the glowplugs is a useful starting point.

If the problem consistently disappears when the glow plugs are disconnected (and consistently appears when connected) it is an uncommon problem but a useful pointer. It might be that the glow plugs are working fine but nevertheless the current drawn is sufficient to tip the scales and drop the voltage too low. But it must be at least possible that somehow the glow plug circuit is drawing too much. A clamp meter reading on the battery cable and on the glow pug cable immediately after the relay (both when heating) would be interesting.

Was this the occasion that you fitted out of date extinguishers purposefully in the hope of catching out the examiner? And then complained to the BSS that your boat had passed - before realising in-date is not a requirement. Did failing to meet industry standards result in the insurance being invalidated?
