Probably because they know perfectly well the Late for Sure Limited is going to get to Worcester hours behind schedule after trundling 1000 miles from Chicago and they don't want people assuming otherwise.

The obvious solution for historical signs like this is a plaque that says something like "This is a historical sign"

Someone caught the Wendell derailment on video. It's like watching a train wreck.

Looking at the damage to the Type 7 vs. the Type 8, I know which one I'd rather be on in a crash.

Electric buses don't "putter". :)

I really like this headhouse design, it's similar to Aquarium's. I like headhouses where it's obvious that you're going underground.

Oh, that's interesting, they're planning to replace the existing Appalachian Trail bridge over the Pike with a combined trail and wildlife crossing. That'll require some clever design. From the grant statement: I kind of doubt that they're going to design in separate trails for thru-hikers and...

The existing rotary isn't under the highway, it's 100ish' to the east. I have to loop all the way around it regularly, coming back from Franklin Park Zoo, and being able to just turn left onto I-93 would be awesome.

One of the options presented in the, er, presentation is a diverging diamond under I-93. I'm a bigger fan of SPUIs for no particular reason; one of the problems with them is that the large paved area can make snow removal problematic, but presumably that's less of an issue under an overpass.

I find it astonishing that quad gates aren't required on Class 6 track. It's easy to misjudge how much time one has to go around the gates (not that one should ever, ever do that), because looking up the tracks you really can't tell how fast the train is going.

That makes sense. You want the crossing to be at the departure end of the platform, where the train is already stopped.

Not if they have to stop there for some reason.

I'd think it should be fairly easy to build an EMU with a (relatively) small battery in it to bridge electrification gaps at too-low bridges. Probably need some automatic mechanism to drop the pans at the right time.

My older kid did one of these spontaneously when they were 7 or so, it included all the subway and bus routes we typically use, the Museum of Science, Children's Museum, Aquarium etc. It was nearly 100% topologically accurate.

Wow, those really are recycled chunks of overpass deck. That's hilarious.
