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?

Yes, any test based on hauling vehicles is more of a test of the properties of the vehicles than of the locomotive's power.

It's been my intention for ages to rig up a simple quadrant to link a loco to a cheap electronic balance - one of those things that I might never get round to.

On the subject of rubber and its alleged variance due to being 'a natural material' - other than specifically latex items, there is almost no such thing as natural rubber these days and it would be a rare loco indeed that used anything other than totally man-made plastic as a traction tyre. If you could find a real rubber tyre, I'd warrant it would be well perished and virtually useless. Even brand new tyres made from natural rubber wouldn't last more than a few minutes running and are almost totally defenceless against rotting on exposure to oil. Even if never run, natural rubber perishes in a very short time frame simply due to oxidisation.

Even the best quality synthetic plastic tyres can't be guaranteed against wear and tear or even to resist some lubricants and it's for those reasons and others that I don't much like them personally, though it has to accepted they can do wonders for traction!

Spot on!

I faintly recall having an old loco that did not have wheels specifically designed for tyres but which nevertheless had a tyre or two on it. It was utter garbage and I think was either given away, lost or otherwise canned.

I am not fond of tyres, but I do have a bunch of newer locos that have properly designed wheels and tyres that have given no bother. I think some of my distaste might be psychological. If I didn't KNOW they were there, I might be more content.
