Lowell to Ayer is single track, except for a a passing/set out track at Westford that is about 1 1/2 miles long.

Are you saying the existing line is 60 mph? I drive by it frequently in Tyngsboro and Nashua, it's looks like 10mph track.

I still say the condition of the bridge deck that truck had just gone over is horrible, like speed bumps on an Interstate Highway. https://goo.gl/maps/srnbvGi8Y7P1yif37

The bridge decks on 495 in that area are in very poor shape it's a rough ride even in a car, lots of debris on the shoulders after being ejected from trucks, etc.

How do you design a sewer drain into a device that moves vertically up and down?

It's not just any road it's in WESTON. One of the biggest NIMBY communities in the Commonwealth.

Can we talk proper english here. What is an ER Down Easter? What is pax rail? Ayer west and the last 10 ish miles to Haverhill? ( its about 35 miles Haverhill to Ayer) What route is Worcester-Ayer -Fitchburg Secondary? Can we construct a complete sentence ????

After the very well designed reconstruction of the Crosby Corner intersection there was hope this trend would continue west. The Taylor Rd/ Piper Rd. intersection with the large available land would so easily be converted to a overpass for relatively little money.

Agreed but at some point they are going to get tired of seeing gridlocked traffic blocking the roads and driveways of Concord.

Five MPH EB in the morning, five MPH WB in evening for 1 to 1.5 miles either side of this roundabout, Barrett's Mill Rd. ,Commonwealth Ave., Rt 2A from Acton, Lowell Rd Concord all a mess. The Commonwealth owns 98% of the property around the roundabout and has been doing preliminary designs for...

Picture #2 is RT 9 EB at J-Way, Brookline -Boston line.

I like trying to read the ad posters in these pictures, on the right there is one for a Charlie Chaplin show at the Boston Theatre. I'm interested in the one at the end of the stub track, can anybody read it?

OK I missed the sarcasm in your post, I understand. We still need an explanation from a railway traction control expert involved in this project.

I was hoping someone with more knowledge about traction power than me would have responded by now but your are so totally wrong. This is what is known as a "negative return cable" . Search google if you wish but good luck.

I'm not sure my links will work correctly but here is an answer to the elevator question, they are performing the proper safety procedures required by law. 556 pages for you guys to read if you want to...

I hope they accounted for when the sun hits the snow or ice covered roof the chunks sliding off or water refreezing on the ground.

Enforcement of no truck bans these days is pretty much non-existent, until the offender causes an accident. Take a ride on Route 495 nowadays and watch all the tractor trailers ignoring the left lane ban.

KISS (Keep It Simple Stupid) I can't wait until the media get's a hold of this.

Special track is turnouts and crossovers. Renewal is kind of a vague term to use, it could mean repair of existing or complete replacement.

Since that drain is on a bridge it categorized as a scupper. Mass DOT has a different set of standards for bridges. Found Bridge Manual Scupper Details ( I don't know if this current standard) it appears to show the grate should have been installed rotated 90 degrees...
