Is it possible to hide a 2 turn helix with structures? I would like to avoid the "helix in a mountain" route. Can someone give me guidance on how this is done specifically the entry and exit points? Pictures would be super.

Thank you.

I have three assembled Central Valley 150' Truss Bridge, in HO Scale and would like to use them for a coal branchline that uses 2-6-6-2's and 2-6-6-6's and 70-Ton Hoppers.  I am modeling circa 1953.  If I understand correctly about the prototype of this bridge, it can not handle the load of such equipment.  So how can I "upgrade" these bridges without trying to disassemble them?  What if I change the string that I guess supports some kind of wire or rod with pieces of thick floral wire?  Or are the steel members themselves too small?  A

I purchased some clumps of Silflor in a late summer green. I've got plenty of them though that I would like different colors without having to purchase another $30 dollar sheet.

A couple years back at the Detroit NMRA convention thier was a clinic about puff ball trees and in the clinic the presenter had a source for the Poly Fill used to make the puff balls that was not white, His scource was mail order but the cost was cheep. Does anyone know this scource?  Or have one of thier own? Of course I need the info now and that is the one hand out I can not seam to find.

I know MicroMark sells it but the cost of what they sell is just nuts.
