Keeping up with news from Honolulu, although I moved away several years ago, the latest issue the under construction light rail will require trains to slow down at turnouts.

"HART says the rail has a new, major glitch in which the wheels on the system’s driverless train cars don’t properly fit at the track crossings. "

Wheel / Gauge problem

There's an old maxim in project management: Fast, Good, Cheap...choose 2.  In the case of HART it's choose 0.

Not Fast.  Project was supposed to be completed in 2020.  Now they're talking 2033.

Not Good. As noted, the wheels are literally coming off!  There have been countless technical glitches, some laughable bordering on pathetic.  And the scope of the project keeps shrinking. You'd think you could hop on at Honolulu Airport and ride it to Waikiki.  You'd think wrong.

Not Cheap.  It was supposed to cost $5 Billion.  The budget is $11 Billion and counting.

Any photographer who knows anything about photography will tell you the photo is taken with a telephoto lens which has the effect of compressing the view to look like the image you see.  A wide angle lens does the opposite and stretches out the image.

On a traditional 35mm camera the standard lens is 50mm which is typically the view angle the human eye sees.  Anything outside that range distorts the image.  In the photo posted, I suspect it was shot with something in the range of 400mm.

Furthermore light rail vehicles can take tighter radii, climb steeper slopes, and are generally built around existing infrastructure.  I don't see anything in this photo unusual. 

However, as is typical of this forum, we need to find a problem for every solution.  From reading the article it sounds like the issues are serious enough without adding additional nonsense.

You can see the original photo on Wikipedia here.

Edit: if above link doesn't work, try this one...or go to the Wikipedia entry for HART and the photo is there too.

The photo metadata says 200mm lens.

The metadata doesn't have the GPS coordinates of where the camera was but I marked up an aerial view with the arrow pointing to what the camera saw.  You're seeing about 3 miles of the line which is elevated at that point and follows Route 99 (Kam Highway).  The blue is Pearl Harbor.

I never thought to check the metadata on the photo.  Good call.  There are not a lot of DSLRs that record GPS and I turned the GPS recording function off on my camera.
