60103 crossing North Town Moor, Langport about 45 minutes ago.

And folk never learn!  First one on the girder bridge crossing the River Parrett, North Town Moor, Langport (and two HSTs^▸ (High Speed Train) passed him before FS turned up)!; second one from the A361 overbridge just north of Cogload Junction.  Feel free to copy and post to Twitter, Farcebook, etc and shame these idiots.

In contrast, this spotter, known in this parish, was spotted behaving impeccably on North Town Moor, Langport:

The last photo from my chasing of Flying Scotsman. Taken about 30 minutes ago as 60103 passed the site of the former Langport East station. Very low light so I dialled up the ISO and used my widest aperture lens. No chance of freezing the action, but I quite like the result.

And perhaps a dipstick!.

I wasn't in the aircraft. 

If you mean the graduated metal rod, they aren't used in Piper Cherokees, which is what Chris and Paul were flying, as a matter of routine. There are metal "tabs" fitted in the two tanks below the filler hole. With the fuel touching these, there is, IIRC^▸ (if I recall/remember/read correctly), 18 US gallons in the tank. Filled to the brim, there are 22 US gallons per tank. There are two fuel gauges, one per tank, which are said to be accurate only when the tank is completely full or totally empty.

There are two important sayings regarding fuel. You can use almost any fuel except what you left in the tanker. And you only have too much fuel on board if you are one fire.

Back on thread, those are excellent pictures yet again, BNM, and proof positive that you don't have to trespass to get good shots!

Had to change trains at Woking today at about 6.20pm and had a 3 minute connection. Whilst waiting for the Portsmouth train I saw a green steam train coming towards us slowly. I wondered at first if it was Tornado but then read Flying Scotsman on the side. Those around me seemed to be as surprised as I was. Maybe those in the know were at the end of the platforms.

What seemed odd to me was that I couldn't really describe it as a steam train because I saw no white or grey steam. Just the sort of clear steam you'd get from a kettle. Is that normal? Perhaps it was being pushed by the diesel at the rear.

I ran into a bit of trouble over my suggestion, in a previous discussion here on the Coffee Shop forum, when I suggested that steam and / or water vapour were invisible. 

I shall therefore refrain from venturing any such opinion here.

It is my understanding that water vapour (being the gaseous form of water) is invisible, but steam is a suspension of fine water particles in air and can be visible. Additionally smoke from the fire (which is visible)  may also be mixed with either water vapour or steam. 

On cold days water vapour can quickly change to steam, but on warm days like today it is much slower and the water vapour can disperse before it changes to steam. 

[Chris from Nailsea]

That all looks fairly clear to me.

Flying Scotsman is spending the week (5th-12th September 2017) on the West Somerset Railway. By all accounts it's proving extremely popular with, thankfully, no reports of trespassing or inconsiderate parking along the route.

WSR in conjunction with the local authority and the AA have done an excellent job with signage, parking restrictions, road closures and temporary car parks.

As to Flying Scotsman itself. She may be great at running at speed, but she was defeated by the climb from Bishop Lydeard to Crowcombe Heathfield earlier today. Weather related rail head conditions led to her slipping to a stand. A banking engine had to be sent from Bishops Lydeard to push from the rear. Apparently such an incident was prepared for with an engine and crew on standby.

Close, but no seegar!

Dry steam (or 'steam' as we purists call it) is the invisible gaseous phase of water; wet steam is steam containing droplets of water vapour, which are visible. Essentially your definitions are pi radians out of phase.

It got stuck on slippery rails:

Actually I see that once again I need to wind my neck in: this diagram explains it all far more eloquently than I can:



In short: there is no such thing as steam. Interesting stuff, water. Unlike the Flaming Wastomoney.
