LRTC - Ferrobus Chassis Test

The chassis has been built and now it's time to see which drive method I will use for the final model.

 

I can't say how pleased I am with the results. I genuinely expected the model to struggle on 4-wide gauge curves, especially with the fixed rear axle, but it seemed to breeze it. I'd even laid an outer oval of dual-gauge track with R40 curves in the full expectation that it wouldn't cope at all, but as things turned out this extra track was only needed briefly, and then only to check if the model accelerated on straight track (it didn't).

 

So now I'm facing decision. I like the power bogie because it is a purer engineering solution, and I'm pleasantly surprised at how well the chassis works with a fixed rear axle. But does the small advantage of the power bogie justify it's use when the prototype does not use one? Thoughts...?

 

Apologies for the poor quality of the video. My ancient camera isn't quite up to the challenge of videoing stuff at floor level.
