PRR single and double track Catenaries?

[jadebullet]

I am just wondering if anyone knows where I can find any catenaries that would work on a set of PRR tracks. I know that there are 4 track ones, but I cannot find any that would work on a single or double tracked main. Any help would be greatly appreciated.

I also need help finding a cat to use on a Truss Bridge.

Thanks in advance.
