The higher detail shots in google earth are aerial survey not satellite, hence the more limited coverage

Ok i am sorry for adding another comment to this posting, and i apologise to the forum admin for reviving an old posting.

As i said before "i have been doing some armchair trainspotting", and i have come across something really strange.

Start at Exeter St Davids, follow the mainline north away from the station, at the junction stay right, after a short while
you will see a steel bridge over the river next to a power pylon, go on a bit further and the river loops back beside the line,
a bit further on there is a "hst" on the down line heading towards Exeter.

You will notice that this train only has one power car at the back, there does not seem to be a power car or locomotive at
the front.

Any ideas why this is? fault with google satelitte perhaps?

The images are taken over time and matched in software to give nice edges. Thus if the HST was moving it may well have only been there for one of the images.

Wait till this page loads, then press the up arrow and watch summer change into winter in an instant.

Looking at the image itself, it does appear to be a photo-stitch error.  The coach is at an angle and the end is slightly blurry - and you can see shadow behind it where the sun is shining from (presumably the car behind it that is cropped off). Also you can kind of see a bit of sleeper shining through the car that is shown, presumably part of the blending process.

If I am right and this train is on the down track, it is the leading power car and at least two cariiages that is missing.

That's good spot though Reuben - and exactly what this thread is for!

Very neat.  How on Google Earth did you find that???

My free range eggs had an address on the box, so I was checking that the hens were actually allowed to roam free. The postcode on the box got me close to the farm, but I had to wander around the roads to locate it. That's when I came across the summer/winter scene. I did find hens in a field just around the corner. 
Google streetview is also useful for finding out if model shops are real places too.

hi all
going back to the OP i'm not 100% sure but i don't think google updates it's images every 90 minutes.some of their images are years old.i found this out when looking down on my old house.my friend who lived opposite was having a lot of building work done and the view showed his house in it's old state.

cheers

the historic imaging time line is useful, large areas are covered by 1945 aerial photos.
ok so they are a bit fuzzy and not very zoomable but still nice for working out old depot layouts.
not sure which side took them, us or them ;o)

Whoah! I'm certainly not saying google earth updates every 90 mins, like you say: some of the images are years old, but each orbit of a satellite takes 90 mins, so it could be that adjoining bits of the map are 90mins apart. Having said that, I have no idea are taken by consecutive passes anyway, so they could be hours or days apart. Presumably many passages over a given spot are useless because of cloud.

You folks in the UK must have a different Google Earth than we have in Australia, where I live a neighbor that hasn't lived in our block of flats for over 12 months still has his car parked in the driveway

It seems that most of you are unaware of the fact that by far the majority of the satellite images were taken, in the late fifties, by Soviet space cameras.
I know this to be true because the shots of Manchester have the sun shining in many areas, and as we all know, this last happened in 1959 !

I am currently making a model of an Avro lancaster Bomber.  Don't worry - it is 1/144 scale and will grace the sky above my layout soon... but while looking for pics to use for paint schemes I found this on Google Earth.  I didn't actually find it myself...

Pretty cool though - what are the odds?
