Mystery solved - It's the Low Frame 4'1" Arch Bar Freight Trucks.

I am looking at building some kit wagons and want the same trucks (here in Australia we call them bogies) as those on the On30 18' Low Side Gondolas. So my question is which is it - Arch Bar Freight Trucks or Low Frame 4'1" Arch Bar Freight Trucks or Vulcan Freight Trucks? Can anyone help?

Thank you, that clarifies it.

Thanks for the reply but except for your comment that it is part of the prototype I was then lost. I assume that Audio Assist and CV are DCC terms? If that's the case, and as I run DC I guess I can't change the prototype?

 

I'm recently new to Bachmann having purchased the Baldwin 2-6-2T, Spectrum On30. I run DC (saving up for DCC), both the front and rear engine headlights shine constantly and I'm wondering if this is the norm or should only the headlight shine in the direction it is going (as per my non Bachmann engine)? Must admit it was a very pleasant surprise to hear it!
