Likewise we were on the 9:25 am, out of North Station on Saturday (9/17) for one of our regular day trips to Portland.
This is a very popular train year round, and as usual it was sold out.
The Dome was opened just after the Anderson stop, and there was a mad dash for it, the Lead Conductor announced ground rules in advance, but as the prior posted mentioned
there was a contingent of obnoxious, and I'll ad socially deficient, rail fans that refused to leave the dome to allow others to enjoy it.
We did ride it from before the Wells station, and into Portland, and that is a beautiful stretch from the ocean views at Old Orchard Beach and the Salt Marshes just before Portland.
The car itself is a treat to ride, and I'll add if you have a chance to experience it do so, the reality is the car is old, and you don't know how long it will last before it has to
be withdrawn from service.
