Measurment Help 4

Another set of wagons from the Transarctica game and another opportunity to guess their sizes
(Wonder why I write here when only a few people read this.......)

They are similar sized wagons but with different purposes.

The Top one called XL Barracks and able to carry 80 soldiers
and these are my calculations:

Length: 50.5 Meters
Height: 12.5 Meters
Weight: 100tons

The Bottom one while similar have a very different purpose of transporting Slaves, 100 in fact for usage in mining, mammoth herding and so on.
And these are my calculations:

Length: 49 Meters
Height: 11.75 Meters, 13.75 Meters with Turrets
Weight: 85tons

As usual I wish to know your ideas for the size of the rolling stock

These are from the game and I did not edited it one bit except resizing
