110 MPH corridors

Postby travelrobb » Sat Sep 01, 2018 10:18 am

Hi all-

Hope everyone's well. Who here can tell me which corridors currently have 110-mph MAS, as well which corridors are currently being upgraded to 110 mph MAS? If you know, I'd also love to know about how many miles of 110-mph running exists on each route, and bonus points for the number grade crossings at 100 mph.

Thanks!
-Robb

Outside of NEC you have:

Keystone Philly - Harrisburg (NEC extension really)

Empire Corridor Hudson - Albany, Albany - Schenectady (and 100 mph briefly west of Schenectady)

Springfield line in Connecticut as of about a month ago

Michigan City, IN - Kalamazoo, MI or somewhere thereabaouts

I think that's about it. For a brief period there was a 15 mile demo high speed stretch on the much hyped Illinois route, but that's back down to 79 mph.

Will Michigan eventually be 110 mph to detroit?

17ish miles on the Hudson between MP 124.3 and CP141 of 110mph. 6 grade crossings one of which is not protected by lights or gates ALB SDY a little more than 7 miles of 110mph 3 grad crossings. SDY to CP169 8 miles 100mph 4 or 5 grade crossing inside the two sections of 100mph of which if memory serves me 3 are unprotected..

They're working on constant tension catenary between Trenton and New Brunswick on the NEC so that stretch will eventually be 110.

The upgrade will raise max speed from 135 to 160 mph on the New Jersey straightaway.

A random memory from running Amtrak F40PH powered trains between Schenectady and Hoffmans: some of the units did not have working speed indicators, so we would get an inkling of when we reached the century mark when the lids of the sand recepticles on the short hood started to bounce up and down. True story!

I also operated CR work trains on that stretch as Amtrak/NYS was starting to rehab the line after many years of PC-initiated disuse. As we made our way along, dropping ties or rail, we would encounter people in their back yards who had purchased their properties along the track thinking there would never be trains there again. They were outraged when we told them the trains would be screaming through there at 100+mph in the near future. Lesson: never assume the realtor knows what she/he is talking about with things like this.

Never believe what a realtor says, period. They're about a 1/2 step above used car salesmen. They all also figured out how a wide angle lens makes every room look BIG.

When I was looking years ago, a realtor at an open house in Bloomingdale (NJ - it's like no other town in the world...) was telling me how NJT was gonna have a commuter rail line in the area in another 5 years (HA!) and how this somehow justified the awkward house layout (Not the worst I've seen, though), and the taxes (holy $#!T).

Knowing better, I decided to look in West Milford, instead. I'd rather be in Morris county, but at least I've got a nice place for now...

Another tidbit from the South side of Alb-Renns is that as the trains blast through Castleton at 110, the pigeons that hang out by the track were contiually culled from the population at a high rate. It took me a while to stop cringing at the sound of multiple rapid-fire collisions with the birds.

I believe it is safe to assume (1) Amtrak’s Chicago to St. louis “Lincoln” service route will eventually allow 110 mph speeds and (2) All Aboard Florida’s north of West Palm Beach will be built soon will allow 110 mph speeds, with the section between Orlando and Coco will allow 125 mph speeds. Otherwise, that’s it for now besides future faster than 150 mph trains in California and Texas.

Occasionally I read questions where HSR trains should be built. This 2010 or so report answers that question for me, maybe it will for you as well. Here is a list of city pairs with the most “daily” airline passengers within 500 miles.
https://fas.org/sgp/crs/misc/R40973.pdf
From Table 5 on Page 24 of the report:
1) LA to SF, 13,838 passengers, 402 miles (CHSR)
2) LA to LV, 5,537 passengers, 275 miles (XpressWest?)
3) SD to Oakland, 4,965 passengers, 505 miles (CHSR)
4) Boston to NYC, 4,550 passengers, 211 miles (Amtrak Acelas)
5) Dallas to Houston, 4,294 passengers, 247 miles (Texas Central?)
6) D.C. to NYC, 4,166 passengers, 237 miles (Amtrak Acelas)
7) Chicago to MSP, 3,527 passengers, 407 miles (Amtrak Empire Builder)
8) D.C.to Boston, 3,369 passengers, 431 miles (Amtrak Acelas)
9) Buffalo to NYC, 2,338 passengers, 417 miles (Amtrak Empires) 110 mph max
10) Chicago to Detroit, 2,280 passengers, 278 miles (Amtrak Wolverines) 110 mph max
11) Atlanta to Orlando, 2,064 passengers, 440 miles (no direct train service)
12) Dallas to SA, 2,006 passengers, 277 miles (Amtrak Texas Eagle) 79 mph max

Remember, these are airline daily passengers data, the Amtrak Acelas probably get as much and so should Amtrak Regionals on its’ NEC, so one could triple the amount of daily passengers to reflect these city pair strengths.

Another interesting statistic to ponder is out of the top 12 City pairs, Amtrak doesn’t provide direct train services on three of the (25%); #2, #5, and #11.

One wonders if Amtrak should be looking at starting an Atlanta to Orlando train service instead of restarting NO to Orlando?

Just think how much faster passengers could get to destinations if every route listed could have just 110 MPH running except for station stops ? Most routes do not even average 50 MPH. You could get that 110 average by having just a few 125 sections. Get rid of all slow spots and passenger rail becomes competitive to autos and short haul air line routes. That does of course require a minimum of 2 main tracks and more in some places. Even the NEC does not meet that average. Just get all segments to 110 MPH and the HSR sections will do their job.

Mathematically, and usually also for financial and reliability reasons, increasing the speeds on lower speed sections raises the average speed on a route much more than raising the top speed does. For example, this is one of the reasons the B&P tunnel in Baltimore needs to be replaced.

And the Metroliners tested there at 165-175 50 years ago.

You'd have to be willing to buy equipment that can actually accelerate, though. More along the lines of the British HST 125 sets. Superliners and P42s ain't gonna cut it. Of course, none of this is impossible, if you're willing to think outside the box...

As far as '160' MPH in NJ. That's nice. It does nothing for running times - you won't spend more than a minute or two at those speeds (assuming you get there). The money would be far better spent getting rid of that stupid S curve in Elizabeth. The catenary rehab is worth it, though. Hopefully they bumped the insulation up to 25kv, even if the clearances aren't there (yet).
