Big Cat caught on Video by PC

I don't know whether this empirically proves anything, but you can see how important perspective is to determining the size of an object...
Using the width of the rails is not an accurate way of determining the length of the animal as perspective or parallax distortion means it may seem like the animal is perpendicular to the rails when it may not be.
If the railway sleepers on the track had better definition in the video they would be a much more reliable way of finding out the actual length of the animal as the cats legs all seem to be making contact with the rail meaning that the cat is aligned to the rail and therefore approximately perpendicular to the railway sleepers. Using the foot contact points as distance markers it would be a relatively simple task of counting how many sleepers (and/or sleeper gaps) the animal spans and then comparing them to the actual track.

Not sure if I follow what you're saying there, so you may have said this, but if the sample added is taken from a lower angle, the image would have had to have been upscaled a lot more to get the gauge.

Your image is taken from a much wider angle so the perspective is totally different

It definitely looks like a big cat.
What I was should have said really was that where the rails on both pictures seem to align properly the perspectives are different in each picture.
If the original image had not been seen in it's original context and the banks on either side of the rails were bigger many people would probably conclude that they were of the same perspective.
I was just trying to say that merely judging the cat's length based on the track gauge and the length when it appears to be perpendicular to the track is unreliable when proving whether it is big or small.
And even if you moved the perspective of the pasted on picture up or down the cat should remain approximately the same length as it is parallel to the rails, yet if it were perpendicular or seemingly perpendicular to the rails the cat would seem to shrink or elongate.

Just been watching this footage on the Beeb, and yes its bigger than the average domestic....the tail-length is a giveaway too...I would say tis a juvenile (3-4 yr) panther

Because it is. You take those two pics in you post and they are very similar size. remember teh one sat down has it's legs tucked in and it's body is not elongated. There is no way in hell that cat is from one of the large cat familys.
A panther grows to about 7-8 foot. That cat in the pic isn't even1/4 of that size.

If the tracks are 4 ft apart you can see that the stride of the cat is easily enough to cover that distance, never mind the head and the tail length.
How do you work that out? the size is no where near as big as the 4ft.

I think in a country as densely populated as the uk, we would know if their are big cats in the wild. If it comes to light that their was an escaped big cat nearby then fair enough, otherwise it is just fantasy to believe that it is a big cat.
I don't know, there are fairly large parts of the UK where they could live, and even in populated area (especially sparsely populated ones) it would be fairly easy for them to avoid being seen too often.
Think about foxes for example, they are a fairly common problem in many towns etc, but unless you're lucky or have something in particular in your garden you're unlikely to see a live one.
We've got foxes that used to manage to kill our hens/ducks if we forgot to lock them up securely in time - in the 30 years we've lived at the house, and the 5-7 years we kept the hens/ducks we only ever saw the foxes twice*, yet we know they were in the garden with great frequency (going by the number of times I had to repair the mesh on the runs/houses, and the number of hens we lost).
*We've seen birds of prey more than that in the garden (and we're in the middle of a town).

Not exactly, I'll use your method to prove that an object is bigger than itself tomorrow.

lol @ you, a 3-4 year old panther would be twice this size.

london foxes arent that shy but i get your point
beast of bodmin is most likely a puddy cat lol
i think because we have no dangerous animals in the uk we like to make them up
hound of baskervilles style.

I had an entire family of foxes with about 10 cubs living under my shed.
All you need to do is walk down the road in the night time and you are nearly ALWAYS gonna see at least 3 foxes.
