When/where does track have ballast on bridge or trestle?

[rogergperkins]

Here is a first look at the option I selected. These are 3 Kato single plate girder bridges [20-452 with Kato piers 23-017].
I had to expand the span to accommodate the 3 bridges and then excavate to allow the piers to be set on the plywood base.
The 2 inch tall piers were shorted by cutting off the bottom.
The holes in the scenery have been filled with lightweight spackling which needs to dry before I paint it and add ground cover
and grasses.
These were gray bridges that I painted with Polly S Steam Power Black.
The bridges are set at a height to allow the Atlas True-Track to be set on top of the Unitrack; the Unitrack joiners were left in place
between the middle and two end bridges to add stability.

Roger,

You bridge looks just like the NS bridge over I-275 in Romulus, MI just west of Detroit Metro Airport.

This map view shows it ncely from the side: https://maps.google.com/maps?q=Romulus,+MI&hl=en&ll=42.219015,-83.411465&spn=0.001832,0.00327&sll=45.00109,-86.270553&sspn=10.130796,26.784668&oq=romulus,+mi&t=k&hnear=Romulus,+Wayne,+Michigan&z=19.

It has two very long spans in the middle. Ballasted at that length too.

Hi, Roger,

It may just be the photo or even my eye, but it would appear that the left pier is not sitting plumb and is leaning to the right in your picture above.  Truthfully, I'm not a fan of the Kato piers, because they don't really represent anything that I've seen in the U.S.  I'd recommend getting some Chooch piers or making your own.

I have searched for photo of Micro-Engineering plate girders with no luck, thus I do not know if they are an option.
The link(s) on e-bay, that I found, did not have photos.  M-E does not seem to offer them per their website.

For a through deck plate you could use the walthers one. It is short but can easily be made longer by using another kit to splice panel lengths from, you get enough girders to do 2 double track spans per kit. The depth on the girder is a scale 6' deep and as the kit comes the span is 48'.

Left pier WAS askew!    This is one of the added benefits of taking a photo.  I saw the pier was leaning, simple solution because the spackling is not set is to realign it.
Benefit of the spackling is easy to redo.

Let us see of the left pier is setting correctly. 
Had to bring in the heavy equipment to correct the problem.
