It's going to keep getting worse as more sprawl forces regular wildlife to become 'urban wildlife'. Last year's two AEM-7 vs. Thanksgiving dinner incidents in Mansfield, MA weren't an aberration...the wild turkey population along the NEC is exploding the closer quarters they get to people. Same with the deer. What used to stay in the woods far away from any from any human structures now doesn't run from you in your front yard when it's knawing on the shrubs or (in the case of the turkeys) knocking over your trash cans and eating by the side of the road. Take away the habitat, and they gotta do what they gotta do.
It's happening even right inside the City of Boston. Both the NEC and I-93 come into the city through the Neponset River Reservation. Wildlife that used to stay on the reservation now is invading the Dorchester and Mattapan neighborhoods. The southern suburbs have gotten so overdeveloped they're pinched into a funnel taking them directly into the city. The morning MassDOT crews that deploy the reversible HOV "zipper" lane on I-93 have to check every morning when they take the truck out to move the barrier what wandered into the 3 ft. space between the jersey barrier and got trapped by A.M. traffic...like this
baby deer they rescued and put in the truck. And staff at Southampton Yard have found coyotes that have walked all the way up the NEC and Fairmount Line overnight. One infamously a couple years ago got to South Station, walked across the Summer St. bridge in broad A.M. commute daylight, somehow found its way into the portal of the I-90 Ted Williams Tunnel, and eventually got captured (very scared) by animal control at a
loading dock in the Financial District. The Needham Line commuter rail has infamous problems with off-peak commuters getting attacked by packs of aggressive turkeys standing on the platform. And that's just the big stuff...South Station and Southampton Yard have long had large
feral cat populations feasting on all manner of small- and midsize prey that walks up those grade-separated tracks from miles around.
If it's turkey and deer strikes today, it'll only be a matter of time before the coyote strikes start to become a not-rare occurrence. And then there will be the day when a Northeast Regional makes the news for hitting a
black bear, since that population is too invading suburban areas close to the NEC that haven't seen them in close to a century. I mean, other than a direct hit on a window like 904 and 944 suffered last year (though that physics usually requires wings instead of fur to hit the right spot) none of this is going to pose any hazard to the trains. Just squeamish stomachs when disembarking passengers walk past the gruesome scene on the loco nose. But it's not only gonna happen more frequently, it's gonna be seen/heard/felt by more people. Especially on the NEC.
