Re: LIRR to test retrofitting M7s to run off batteries

Posted by Olog-hai on Wed Apr 21 01:55:05 2021, in response to Re: LIRR to test retrofitting M7s to run off battries, posted by Jsun21 on Tue Apr 20 20:06:43 2021.

My understanding is H is more volatile, for example if you were to drop a match in Jet Fuel or Kerosene it wouldn't light. Hydrogen will be more easily ignited

That's not what "volatile" means. The word refers to any liquid that evaporates at ambient temperatures, regardless of flammability. Water is moderately volatile, but clearly not flammable. Hydrogen will never be a liquid at ambient temperatures, its boiling point being way down at –423.2°F.

I think LIRR MUs run about 2K miles per week and a million per decade.

No, accurate words. Two different drivers in the same car will drive differently. One may use the AC, the other may not. One has a heavier foot than the other. One plays the radio, the other does not. It's no different than a conventional car driven by two drivers - each will achieve different mpg based on the way they drive.

In my post, I mentioned that it pulled the whole Lake when the construction at Albany was going on. The Boston passengers did a cross platform transfer and the trains were not joined. The Boston sleeper, coaches, and the cafe car went to NYP during that time period. I don't remember if they hauled the second baggage, back then the Boston section had one. This was not a short term event, it went on for quite a while.

Like I said a few posts ago. Electrification should be on a case by case basis. Croton-Harmon/Poughkeepsie is basically flat terrain, aka water level route. Acceleration rates are a non issue on that line. The reliable and comfortable equipment coupled with a superior on time performance results in minimal complaints. Nobody is (was) whining wa wa wa wheres our 3d rail??
On the Harlem line, theres a big uphill pull from NWP to Chappaqua & stations were closer together. 3d rail was justified there.
Same with the Pt Jefferson line. That branch is the closest to mountain railroading with its hills & closer together stations. That coupled with that crap they use as "reliable and comfortable" commuter equipment there begs for 3d rail to be installed there.

According to LIRR Today, Ronkonkmoam eletrifiction in present value dollars cost $15.5 million. Upcoming Central Branch electrification, which is next to useless for any passenger, will cost $22.4 million.

But Eng keeps saying electrying everything (169 more miles) would cost $17 Billion ($100 million/mile). The guy is a fool.

The low height of the 63rd st tunnel really puts a monkey wrench in some alternatives. The M-8 cars (proven design, good track record)can do cat and third rail, building with over-running shoes is easy, and cat would be considerably less expensive capital cost wise (albeit with slightly higher ongoing maintenance costs) but will never do ESA, the cabinets/pans make them too tall. They cost more than a stock M-7 or M-9, but after the battery mods and charging infrastructure probably not.

That's the way automobiles worked for about 100 years. I'd imagine that jetliners worked that way too. I think the biggest innovation of the 787 was its composite, rather than aluminum body.

This BEMU with the M7 experimentation is "sexy" to give they impression they are proactive and current with tehnology, with fear-mongering "$17 Billion" for 3rd rail extension, which is mundane. Service will still suck.

As someone who drove a Tesla all winter I can confirm that the winter decline in range is overblown. I think that the biggest hit to range in the winter is the heater, which unlike in an ICE car, isn’t free.

False arguments. Use of EMUs versus diesel push-pull is about way more than grades and adhesion/acceleration. And a flowing river's valley is not grade-free terrain.

BTW, another pro-MU argument is increased number of on-board bathrooms, which makes longer journeys more relief-filled, to turn a phrase.

You really think everything is always the same?

is the M in MDBF a "weasel" word, since it's "Mean" as in "average".

Tesla has a list of things that can help keep the battery charged longer in the cold. keeping the car plugged in till just before you leave, scheduling your departure time in advanced, and setting your destination as a supercharger.

The BEMU converted M7s, running on, say, the Oyster Bay, will be off the third rail for a maximum of 26 miles of travel if they don't put in a charging point at the end of the line. They'll be fine.

17 billion is a number to scare the politicians away. The third rail can be laid while any tie replacement is done, the Z bonds can be done while any signal upgrades are done (or even without, probably. All the platforms are high already. Substations are a catalog item, even ones that can accept regeneration.

After Eng's March 8 scheduling bullshit, the polticians should be scaring him, or else they are dumber than he is. He is like a child playing with Heathkit who thinks he's a NASA scientist.

Port Jeff line platforms are platforms are 10 or 12 cars, the abandoned Greenlwan platform is there, no staion need be moved, CTC is there, parking lots are there, passing sidings are there, though Greenlawn's should be interlocked, but this would be a cakewalk compared to Ronkonkoma.

All for five times the price, right?

The cheapest Tesla is just under $40K and gets (if I'm lucky) half the range of the car I drive now that's way under half the price.

The cost of ownership of a Tesla is significantly less. Not only does it never need an oil change, and doesn’t have a transmission, but as I keep pointing out, electricity is cheaper than gas. I pay a negative number for “fuel.”

Tesla says you should get about 500,000 miles from it.

Hmm. Quick googling suggests a range of 300 miles and 300-500 recharges. Call it 400 on average.

300 x 400 = 120,000, not 500,000.
