What is the average mass of a train?

Question

Hello, I have a Physics assignment and I've been researching for hours and hours just to know what the average mass of the train / electric train is. [example: MRT / LRT <--philippines] ... there's this website w/c has the answer like "6.4x10^5 kg".. i don't know and i don't have a clue. Please answer my question! It'll be greatly appreciated!

Here's the full question:

How much mass is needed to transport one person? If the vehicle is shared, divide the total vehicle mass by the number of passengers. Total vehicle mass includes machine, carried fuel, driver and passengers. The driver does not count as a passenger if s/he stays with the vehicle. (mass in kg)

what i need: the mass of an average train w/ machine and carried fuel.

thanks! hope you guys can answer ASAP!

Answer 2

This question is hard to answer in general.

There are many types of passenger trains, many types of engines and carriages. Sometimes the same type of carriage is used for first-class as well as for second class (with ~50% more seats, so the weight per seat is much less). Additionally, the ratio of engine-weight per passenger strongly depends on the railroad-line (e.g. on steep mountain-lines you will need much more engine power).

Weights can start as low as ~13t for a light railcar, that offers room for about 40 passengers and go up to far more than 1000t for long trains consisting of 20 or more carriages (space for 2000 people or more) that need to be hauled by two or three engines...

Depending on the circumstances the answer is somewhere around 250 to 800kg per seat.
