The ties under rails in the crossovers of the lesser used interlockings has a service life that is the same as the ties under the mainline rails.So you are saying tie-life is more a function of age in years than usage [# of axle crossings...]???

They degrade from exposure not from the loads placed upon them. The rate of degrading depends on the type and amount of exposure (contaminated ballast, drainage, direct sun light. NS routinely replaces the ties on their line that runs from Newark Delaware to Pokomoke City Maryland over here in the sand box. The line sees one train a day south of Harrington Delaware.

Metro's final report card for Surge 7 on the Red line is out: http://www.wmata.com/rail/SafeTrack_Sur ... ort_v3.pdf

Another WP report discussing FTA's findings that Metro is not doing a good job during Safe Track. https://www.washingtonpost.com/local/tr ... story.html

The reports also included myriad complaints familiar to those who follow Metro’s daily woes: Clogged drains. A loose third-rail insulator. A front flagman observed “in a sleeping position.”How long would that last in a real railroad?
Metro has announced revised dates for the remaining surges in 2016. It has not announced new dates for the 2017 surges. http://www.wmata.com/about_metro/news/P ... aseID=6168

Here is an interim report card for Surge 10 on the Red line, ongoing until Nov. 22. https://beta.wmata.com/service/upload/S ... port_1.pdf

WP is reporting that Safetrack may extend past its original 1 year deadline of March into June. Coordination problems and worker fatigue have contributed. The budget for the project has also been revised upwards. See https://www.washingtonpost.com/local/tr ... story.html

I'm shocked, just shocked, that they found things were in worse shape than they first thought; and that it would take longer/cost more to repair......
FTA is reporting a host of problems with Metro. http://wtop.com/tracking-metro-24-7/201 ... o/slide/1/

Metro has revised its final two surges, focusing on the Orange and then Red lines, so that they are complete line shutdowns rather than single tracking. https://www.wmata.com/about/Surge-15-News-Release.cfm

I found it intriguing that they would cut Silver Line service and have that line end at the Stadium-Armory pocket, and sending the Orange to Largo. The silver line already provides more trains during rush hours than the Orange, and it would prevent some confusion as the Silver line already goes to Largo anyway.

In short, they don't trust the operators to obey the Rule One. With the main line closed east of there, there's no such hazard.
While SBJ disagrees, that's the issue.
BTW, I was talking to an experienced rail operater at Cleveland RTA, and he said that there, any operator running is red is fired, period. No union outrage. It had happened a few weeks before.
He did say in some few cases, the operator is invited to reapply after a full year, but they would then be a new hire.
