I would if I had it.
This is simply a Photoshop job based on a preliminary version FIRST released a year ago.
The easiest thing to do to get a hi-res version is to rebuild it at the higher resolution (what pixel count are you thinking of?).
The existing one was constructed at 1200x789, then it gets fuzzy from the lossy jpeg compression I used.
Some of the images are hi-res (PCM/VRM/PDP/roboRIO), while others are low-res and would have to be retaken. That is a pretty quick job.
The only hard part for me is making the line crossings look pretty...
