Whether a weight can be moved at all is a question of torque & gearing. The speed of ascent is down to horsepower, - the rate at which an engine can do work in a specific period of time. A truck engine develops its power at 10 times the rotational speed of a traction engine. Therefore to equal the HP of the truck engine, a traction engine would need to develop 10 times the torque @ 1/10th of the rpm. Boadicea develops 4335 ft/lbs working compound as here, or 11877 ft/lbs working simple.
cont, - this compares with 1800 + ft/lbs of the truck engine, which has much shorter gearing & a torque converter to allow it to rev to optimum rpm. Obviously we should expect some progress in the 90 years that separate them, but don't underestimate the gigantic turning effort of Boadicea's cylinders. No truck engine in the world could move a tiny fraction of the weight this traction engine does at the rpm at which she achieves it.
lol this is old school!

You'd think one of those gigantic steam engines would be enough >.>

It is! Boadicea pulled all 140 tons uphill on it's own using 1/3rd regulator.

Yes but at what speed,2mph?

They use both as they want one for breaking, and it looks cooler

I'd like to see those steam engines drag racing.
( No not IN drag )

This is cool but I wish it had the sound.

Atleast put the semi in gear and make it interesting.

It would just drag it along, but it would break the truck with that load on the back

where can i find a Video of one of these in real action? >.>.

this year a showmans engine nearly half the size of bodacia pulled that loco on its own!!!!!!!!!!!!!!!!!

It's not the ultimate tractor pull.
in 2006 an engine named 'bodacia' pulled a loco like that on her own.
