But someone somewhere knows how high that bridge is going to be and it must be higher than anything that will travel under it...If not? Oops.

the overpass has legal clearance over the UP main line. That part was done correctly. The problem is Cap Metro's own interchange track. That spur connect the existing Austin & Northwest track (which crosses the UP at the McNeil diamond) with the UP. The spur line has sub-legal clearance as the overpass was designed.

4 feet difference? 23 vs 19? People die. Especially at highway speed.
Dont wish for this type of accident to happen to a double stack.
I believe much was made of the light rail in Baltimore missing a few obsacles by only a few inches.
I should not laugh, I scraped a few objects myself... note I said scraped...
Wonder what else the toy train people failed to think about/on before they lept?
Scary...

I loved Cap Metros' initial response - "the tallest thing we own is 17 feet." The track in question is an interchange track. Owned equipment has nothing to do with it.
you have to think in 3-D. Engineers used to working in the plan view only can often get in trouble.
Amateurs!
Light Rail people and their consultants are "toy train" people for the most part. A real railroad design guy/gal would've caught that blunder in a heartbeat.
Wonder if a civil engineer loses his license over this? (Practicing outside his area of expertise)
Expensive blunder.
Illinois Terminal had the same problem 60 years ago.
They made an ill advised attempt to stay in the interurban passenger business by buying three "steamliners", two and three car sets of "modern" electric interurban equipment that were to scoot around linking central Illinois cities with St. Louis.
They tried, one time, to take one of the new trains into the largest central Illinois city, Peoria. The top of the train hit the top of their Illinois River bridge. It was a "vertical curve" thing where the train comming off the bridge into the Peoria terminal just wouldn't fit.
Service was cut back to E. Peoria. The "streamliners" failed with the loss of several million dollars and the IT went freight only with diesel power.
Wow, can we get a
DOH!

Looks like Capital Metro overpass clears the UP but not their own spur.
