[quote]This is a new trend, across the transit industry, that troubles me. Like Ed mentioned, a lot of systems, good and bad, ahve been guilty. The worst that I can think of are the Railworks project in teh early 90's, where SEPTA severed the ex-Reading commuter lines for months at a time in North Philly, the Green Line closure and reconstruction in Chicago, the Baltimore Light Rail double tracking, and the Lechmere closure here.
The notion that rail transit services aren't essential is troubling. No one, during the Big Dig, considered closing I-93 for a year -- its too "essential." I wish that the same notion applied to rail transit services. In our own local example, if a highway tunnel can be built under a city while everything remains open, there's a way to build a new subway tunnel entrance ramp without a year long closure. It requires the public/political perception that transit is of equal value and importance, and that transit users diserve the same treatment as highway users.
Please note that while I used the MBTA project as an illustration, this is a problem that extends beyond Boston. [quote]
In a lot of cases, shutting down an entire rail line for reconstruction may be the better option because the job can be done quicker and cheaper if is done all at once instead of doing it under traffic [in such cases could stretch a project to a decade or more like the Frankford El reconstruction].
When CTA shut down the Green Line, it had the Red and Blue Lines nearby to pick up the slack, and the Green Lines's passengers. The Lechmere-North Station reconstruction is rather short, and buses can handle the traffic, and Baltimore MTA's light rail shutdown shifted most passengers onto express buses, in these cases an alternative was available. In the case of the MFSE, there were the local shuttles to Spring Garden and the express buses via I-95 to Center City using Articulated buses. The night/weekend shutdowns basically impacted the weekend riders, and anyone riding at night, outside of the regular 9 to 5 commuters.
During Railworks, SEPTA had the Broad St Subway to pick up the slack since the rail lines paralled the subway in North Philly. SEPTA expanded express service [adding night and Saturday trains], and made the locals run more frequently. In additon they ran express buses to replace the R6, and ran shuttles from R7 CHE stations to CHW stations on weekdays. Also it confined the work to the warm-weather months, which inconvenienced as few passengers as possible. As a result of the shutdowns, the Railworks project saved both time and money.
That is the motivations for shutting down rail lines. In many cases systems can get more bang for the buck, and get the line up and running quicker. Now as far as I know, keeping I-93 open during the Big Dig was one of the many contributing factors to the EXCESSIVELY HUGE cost overruns the project suffered.
