Western Railroad Discussion > New signals on UP's SI line north of SpokaneDate: 11/22/13 10:22 New signals on UP's SI line north of Spokane Author: cpn456 I recently noticed some new signals installed on UP's SI line from Spokane to Eastport ID, a line that is dark territory. Through observation, my guess is that the UP is installing "CTC islands" at sidings, where the dispatcher controls the switches and signals at the siding switch, but the rest of the line is still dark territory. BNSF uses the same thing on the former NP Stampede Pass line.

Date: 11/26/13 08:54 Re: New signals on UP's SI line north of Spokane Author: kalthoff More trains due to increased potash? oil from ND and AB? grains from ND,MN,SAS? Also the CP from Eastport/Kingsgate to the mainline at Medicine Hat is Dark.I don't suppose there is any planned capacity enhancements there.
