Large Scale Central

Whet is you heaviest loco weigh?

General Discussion
#1

I am redesigning some of my bridges and would like to know the heaviest loco on the large scale market today. I am assuming that the Big Boy would be the heaviest but I may be wrong. Some of the new diesels are pretty heavy and I know that live steamers are up their also.

Since my total system includes two 4-6-0s’ and an old 0-4-0 I don’t have much to go on.

I need to know the heaviest so I can test the new designs.

Thanks for your help.

I heard the USA Big Boy(metal) is like 79 lbs, with the tender, spread over a big area though. You might want to get some idea of weight per sq in, rather than total weight. Jerry

My heaviest loco is the Accucraft Garratt at around 36 pounds or so, fueled up - but it’s spread over a yard of track too. The K27 is around that weight too, again, spread out over a yard.

As Ralph Brades notes on the other website- you need to consider the ‘localised’ load.

Thanks fellows, for your response. I had no idea that a Big Boy was that heavy.

I will have to work up a test method that will take the loading into account. I don’t think that the dynamic loading will come into play at this scale. I just don’t want somebodies dream loco to come crashing through one of my bridges, unless of course the video camera is running.

That might be fun to rig one to collapse on cue.

As much as this stuff cost I do not think that would be a nice sight no matter what!!!
Plus you have to consider the amount of modeler effort that goes into someone’s project, ( it is much much more than cost)

Generally speaking I think the norm is three times the largest load then make your model from that figure. 
 Or just stand on the bridge at all of the different areas to make sure it will hold up to the weight of what you are aiming at.
 As long as you are not a 5'6"  foot tall string bean that should work out just fine!!

Accucraft K-4: loco 18.6lbs, tender 5.4lbs, Total = 24lbs. This is before RC, Sound, and batteries are added.
SD-45: With RC/sound/Batteries/1extra weight = 15.6lbs, OEM SD-45 = 14lbs w/o added weights.
