Extremely nice work!  But if I'm already complaining about the price of Lionel's plastic trestle sets, I'm certain that your will be more expensive.  Very impressive though.

IMPORTANT QUESTION!!

Is there a special style trestle designed for Gargraves O-Scale track?

Ponz

Ponz,

GarGraves does not have the strength to be supported only by trestles spaced every 10" or so like the old tubular track or Fastrack.

You will need to support the GarGraves along its entire length either with a plywood roadbed supported by some sort of piers or by structures such as those Joe showed you.

That's what I needed to know Jim.  What about closer spacing, or will that look funny? Now I have quite a challenge because my setup does not follow any specific curve like O54, O42, O32, etc....It's custom laid to an awkward table.

Thank you.

You could probably get away with about 5" or 6" spacing of trestles. But, track without a continuous support is always dicey IMO whether it is tubular on the plastic 110 trestles or whatever else you use.

It wouldn't be too bad if the upper level were a constant elevation with no grades. An up and over like you show would take a lot of custom cutting of whatever you use for supports.

It would be easier and more stable to just lay out your curved track on a sheet of plywood if you are using pre-bent curves (recommended!), trace around it, and cut out the strips of roadbed with a saber (jig) saw about 1/2" outside the ends of the ties.. 

If you are bending your own curves, I'd do it right on the sheet of plywood, attaching the track to the plywood as you go. Then, use the saber saw to cut along the curves creating roadbed strips with track attached. Then you could use whatever style trestle you want to support them. 

The plywood roadbed allows you to space out your supports while providing a much more stable system overall.

Joe that is some fantastic work. 

Thanks Dan

Hi.

Another option would be girder bridges made by BRIDGEBOSS.COM. These are made in most all standard curve sizes and in various non standards including multiple curve arrangements. There are several types of supports to select from also.

See a few examples below. Contact me if any questions.

I don't want to rain on your parade but my thought is that your grade is too steep and even more so since it starts and ends by your switch.

Dennis - Man, I sure hope it's not. If it is, I'm not sure what my next course of action will be. Ponz

I just realized that it starts at the green- I thought it started at the pink. Starting at the green, it appears that it would be about a 4% grade. A train can handle that.

Ponz:

Another idea - there are only two spots where the upper level track crosses lower level track. Everywhere else you could use woodland Scenics foam risers. Creating a slope / adding scenery and or adding Scenic Express foam block walls would look pretty good.

Attached are some picture off the internet

Apologies on my lead time.

Thanks Joe - This project becomes more daunting with each passing day.....Ponz
