The top operating speed will be 160. The FRA mandated that Acela I's would could not exceed 130 in any curve, even if it was designed to a higher speed. I'm told that restriction will be 150MPH on the new trains. That leads to the possibility of the maximum authorized speed of the Acela 2...

One, I am not a troll. Two. Adding a track adds capacity. the track 4 that would be "forced " to merge at Forest Hills would have enabled that Acela to pass the Stoughton or Providence Local it was forced to follow into Boston, It happened to me more times than I can count. And having 4...

It adds a track between Forest Hills and Readville where the faster Amtrak trains can overtake slower commuter trains. The idea of a single branch line entering the main line works well at Canton Junction. It does not appreciably constrain the Needham Branch. Amtrak's top speed in this territory...

This configuration ,with the extra track 4 between Forest Hills and Readville, Rte 128 ,or Canton Jct. Would increase capacity, and expand service with a new station at Clarendon Hills, without radically disrupting service to the Needham Branch .

simplistic and incomplete , but what I'm basically trying to convey

I wish I could draw it what I'm trying to explain.

BTW, a little bird has told me that the new Acela trains have been authorized to negotiate curves up to 150 MPH. The old trains were restricted to 130. This could mean that top speeds for tangent track for the new trains could be even higher between Mansfield and Forest Hills, and possibly into...

My apologies Mr F. New to all of this. The track 4 to which I refer is not the track marked as such on your original diagram. I am talking about the original alignment entering the SW Corridor on the main Line from the west. It would be 4 and 2 eastbound; 1 and 3 westbound. Instead of 3 tracks...

OOPS sorry! Track four will connect to track 2

The railroad's timetable direction for these tracks is east and west. Back Bay station is towards the left of the diagram; east of Forest Hills.In the diagram Mr F supplied, the top track is no. 2 descending to 1, 3 , and the bottom track is actually the Needham branch. That track which is now...

Mr F . I keep looking at your schematic of Forest and see what I consider a huge error. The Needham Branch is drawn as if it is a double track main line merging to a triple track main line. The Needham Branch is.... a branch line! It needs only to connect with a single track at Forest Hills...

I wish I was savvy enough to portray my ideas in graphics that showed my thoughts . But I will try to show them with my words. I Propose running mainline track 3 to where the Needham line now tracks on the platform at Forest Hills. The Needham line would divert directly from that track. It...

Looking back at my posts, I think I have to backtrack, and retract. I am not advocating making Forest Hills a Commuter stop as much as changing the right of way to improve capacity. My bias is towards improving Amtrak's speeds and access through the SW Corridor.

With all due respect Mr F Line. All the professionals thought three tracks and platforms on tracks 1 and three at Forest Hills and Ruggles would suffice., but they had to build a platform on track 2 at Ruggles...... And they had to change the signal system on track 2 there too. ( I was there)...

And, regarding Readville, if Franklin passengers start demanding a one seat ride to Bay Bay, there is no better place to put a flyover from the Franklin to my proposed track 4 than at Readville. Plenty of room.

The track 4 would allow Amtrak trains to overtake local traffic before entering the SW Corridor. The New platform at Ruggles removes the opposing crossover at Plains for eastbound trains stopping at Ruggles. The four tracks where I propose them take Westbound Locals off track 1 all the way to...

Mr. F. I was thinking more my track 3 ( which is the existing Needham line station track) running north of the existing platform and track 4 merging to track 2 just east of Forest Hills. It may allow a platform on my proposed track 4, which would be the south track on your track chart. I think...

Further Adding track no. three between Readville and Forest Hills would make tracks 3 and 4 commuter only while tracks 1 and 2 would be for Amtrak. One could add a station at Clarendon Hills. It would be just like Attleboro.

I don't get your logic. Adding capacity increases delays? Track 3 Forest Hills to Readville would give Franklin trains flexibility to crossover at Readville or Plains. Needham Trains could hold outside of the station (or Franklintrains could hold. Having track 3 doesn't automatically mean Amtrak...
