[quote user="riprap"]<p>Hi again, 1435--</p> <p>Thanks again!! Yes, all of which you write sounds quite logical. Just one last thing: before UP took over SP's line down to Eugene, SP had taken the step of removing two of the three "arms" from the pole lines, but retaining the one last arm. (I know, I'm weird for noticing, eh?) Then, a few years after UP took over SP, they completely removed all traces of the pole lines. How would those developments fit in with your contractual obligation (or would they?)</p> <p>Riprap</p>[/quote]<br><br>Not sure what "contractual obligation" means. <br><br>Removing crossarms and wires is very common. What's usually removed is the obsolete voice circuits dating from when the railroad provided its own telephone network. What remains is just the two ABS wires and sometimes (but not always) two power wires for the signalling system. The wire is removed to reduce maintenance costs (and to get it before the wire thieves do). If you don't remove the old wires, you have to maintain them, because when they break under stress of wind or ice they can and will take out or ground out the wires you want to keep. Likewise, removing the superfluous crossarms keeps them from falling off onto the lines you want to keep, and breaking them.<br><br>S. Hadid<br>
