Locomotive scales

[JasonBModerator @jasonb]

For standard gauge it is just 5/56.5* times whatever distance you what to scale.

* Model gauge divided by full size gauge 4' 8.5"

Chris,

to answer your original question, which doesn't appear to have been answered, but you may have 'sorted' since posting.

Lucky 7 can be built as an outside framed 3 1/2" gauge 'narrow gauge' Forney locomotive. This is the gauge and scale combination in which the 2" gauge prototype is most often built.

Video.

 

 

It can also be built as 'mini' Lucky 7, that is using the drawings for the 3 1/2" gauge locomotive above BUT as an inside framed 7 1/4" (or 7 1/2"  ) gauge locomotive. The difference is in the axle lengths and wheels (which are spoked, rather than disc), nearly everything else remains as the 3 1/2" gauge locomotive. In fact, if you make two sets of wheels and axles it becomes a dual gauge locomotive that can be changed over relatively rapidly.

Video.

 

 

There is also Maxi 7, a 7 1/4" ( or 7 1/2 inch) gauge version, which is an outside framed, narrow gauge locomotive. This is a rescaled drawing set of the 3 1/2" Lucky 7.

Video.

 

 

(And, to further confuse the issue Lucky 7 has been built in 5" gauge, 2 1/2" to the foot, as a narrow gauge Forney, I think by rescaling the 3 1/2" drawings, but you would have to do this yourself.)

Video.

 

Regards,

Phil.

Wow, this is beyond what i wanted. Our track is 1/3 mile long. I run a 5" loco around it and do 30 laps, that should be 10 mile?

I just needed to know how many scale miles i had done?

Maybe i should have explained myself a little better. Sorry!!!!

Thank you for all the brain power used in this

30 x 0.333 = 10 actual miles traveled

Converted to yards is 17600

17600 / 156 = 112.8 scale miles

OR 

10 x (5/56.5) = 113 scale miles

 

Now if you know how long it takes to do that distance you can work out  a scale speed

Thank you Jason, Thats what my wife worked out,

Cheers

The superb Garden Rail show is on at Peterborough Arena tomorrow. It is mainly 16mm but also a fair bit of Gauge 1 (10mm or 1/32). A good place to go to appreciate the distinctions between scale and gauge as they all run on 45mm gauge track.
