Today after work, I crossed over the UP Mainline in Sugar Land, TX where it parallels HWY 90.
They've been widening Hwy 90 here so Union Pacific has rebuilt every road crossing here. Today I noticed something at one of the recently redone crossings (actually still in works too).
Anyway, here's a pic I grabbed with my phone:
The item on the right hand side, looks like a speaker almost. The item on the left however looks like a signal box I've seen used on light rail lines to indicate to cars where it's safe to turn left or whatnot.
This one looks like it's a got big "X" in it. The other side of the road had another one, but just with the speaker looking item facing the cars approaching the track from the other side (towards me).
Any idea what this is for? I thought, perhaps a indicator to trains the crossing isn't clear? But then why a speaker? You can see the crossing gates themselves have 'em at the top of their poles.
I'm not sure if any other crossing's in this area have one of the installed or not.
