A few weeks into Connect2020, riders are enduring the result of some failures of foresight. Planning any train trip requires a 15-minute buffer that makes it nearly unusable for short-haul trips, where the train’s speed advantages matter less.
Long-term failures
The Central Link line is neither futureproof nor robust. The intention to build rails on I-90, though not voter-approved for most of the period of tunnel retrofit for Link, was well-established. A trivial amount of additional track, where it intersects the track in use, could have avoided the current pain entirely.
Furthermore, more liberal placement of switchovers would not only have allowed much lower headways today, but would also have made the system more resilient in the event of car crashes and other incidents on the track (like train maintenance issues).
At this point it is customary to write off all poor pre-2009 decisions as the bad old days. But ST is still poised to make the same mistakes. Already facing unavoidable huge disruptions for Graham St. and Boeing Access Road, it may do so avoidably at the firmly planned 130th St Station, to say nothing of unapproved but likely extensions.
