Safetrack, the monthslong system-wide maintenance project that has seen several safety surges cripple parts of the Washington Metro, has drawn its fair share of ire in the national capital region.
The project didn't treat each line equally, and a CNS data analysis shows that the lines most affected also _________. Surge-by surge, ____________. And while it may have been a pain, the magnitude of Safetrack's literal nuts and bolts is pretty staggering. The amount of supplies replaced during the project is just about as massive as you'd expect.
With the end of this massive undertaking forming a slow but steady light at the end of the tunnel, let's take a look at the statistics behind Safetrack.

Methodology:To calculate the regional affects of Safetrack, line-by-line service reductions were calculated by multiplying the distance from one stop to another by the percentage of service reduced. For example, a 1 mile span seeing a 60% service reduction would earn a "train miles" value of -0.6. This figure was then multiplied by the number of weekday morning peak periods that the specific reduction would be in place. If the reduction mentioned above lasted for 10 morning peak periods, for example, the value for the whole surge would be -6 "train miles." This figure, totaled up over all surges, begins to provide a portrait of how Safetrack affected certain parts of the system. The Washington Metro features many stretches where two or more lines run over the same route. In many cases where these routes saw reduced service, only one line was technically affected. For instance, there were periods when construction on the southern portion of the Yellow Line led to reduced Yellow Line service to stops where it parallels the Green Line. While only one line technically saw a reduction in trains, the perceived result for that segment of a route was a reduction in general, no matter which actual trains were absent. To account for this, "train mile" deductions were assessed to both lines in a route segment. For example, if service was reduced between, say, L'Enfant Plaza and Archives stations, both the green and yellow lines would see a "train miles" deduction for that stretch, even if only the Yellow Line saw fewer actual trains dispatched.
