This item appeared on the Maerklin website. They have managed to get 200 Maerklin locos to pull a full sized DB coach. That would be 1 to 1 scale.

On the area of railways system engineering in Munich took place on 21 February 2007 a sensational experiment. Märklin locomotives of the size H0 on a scale of 1:87 should pull an original-size IC region car of the German course AG over a distance of 10 meters. The car had nevertheless an unloaded weight of approx. 48 tons and measured scarcely 27 meters. 200 Märklin locomotives of the BR 143 with the article number 37433 were available. On 50 tracks, to 4 locomotives each arranged, they were supplied by 50 transformers with energy. To set 3,000 VA necessarily around the IC region car in motion. The experiment succeeded and the 200 Märklin locomotives pulled the 1. Class car evenly, strong over of the Guiness book of the records editorship given distance. The Märklin specialist of the 1. Märklin model course team shifted altogether 625 meters of the Märklin of C-track, pulled 1.5 km cables and set over 3.000 soldered connections. The pool of broadcasting corporations transmission "W wie Wissen" sends the pictures of the preparation and the world record travel on coming Sunday, 25 February 2007 in the 1. Program at 17.03 o'clock.

So if the coach weighed 48 tons and there were 200 coaches, does this mean that each loco was pulling a quarter of a ton?

>So if the coach weighed 48 tons and there were 200 coaches, does this mean that each loco was pulling a quarter of a ton?
Not if the coach is on level ground. The weight of the coach will act in a line running at 90 degrees to the rail on which the coach rests. The locos pulling the coach have to overcome the rolling resistance of the coach along the rail. This is determined by the coefficient of friction between the wheel and the rail and that is where my memory of applied mathematics runs out..... but I'm sure there is at least one member who can pick up the baton and run with it. I for one would welcome a "refresher" on this.

>sort of thing you use to weight fish caught on the rod...?
The same thought has been drifting in and out of my mind over the last couple of months. I even did an Internet search and found that there are many different spring balances available for fishermen to weigh the ones that didn't get away. I guess that a 2kg unit would probably be sufficient?
