Which is heavier, the average train or Stonehenge?

Well each stone in Stonehenge is 44 tons.

The average freight train is 8000 tons.

44 divided into 8000 is about 182 and there are certainly less than 182 stones in Stonehenge so the average train is heavier.

Depends where you are looking and how you define average.
In the Netherlands, passenger trains are more common than freight trains and these

are average trains. Weighs vary from 86 t to 352 t.
What I would consider an average dutch train is 200 t, comfortably less than stonehenge.
I am sure an average train in Australia looks very different.

I can't find the total weight of the Stonehenge stones, but it is not a simple matter of multiplying .
There are stones of various sizes, and only the big 'sarsen' stones have weights around 30 tons.

Hopefully, the following will provide enough additional information for everyone to do the calculations according to their own specifications in order to come up with "their own" ideal solution.

The average weight of a freight locomotive is 146 tons.
The average weight of a passenger locomotive, 134 tons.
The average weight of a switching locomotive 91 tons.
The average electric locomotive on Class I railroads weighed 156 tons.

(All weights approximate to 1940).

The average freight train consisting of 100 cars -- weighs in at anywhere from 12 million to 20 million pounds.

t is said that the stones at Stonehenge weigh in somewhere between 30 tons to 50 tons each.

The giant sarsen stones (which form the outer circle), weigh as much as 50 tons each.
