High Speed Trains Designed to Withstand -40C

CHANGCHUN, Nov. 28 (Xinhua) – China’s high-speed trains that will travel across the country’s frigid northeastern regions are designed to withstand sharp changes in temperature, a chief engineer said Wednesday.

The country’s first cold-proof high-speed trains are expected to run from Saturday and any problems with sharp changes in temperature that once forced Eurostar to halt services in 2009 look to have been solved.

The trains, to withstand minus 40 degrees Celsius temperature, will travel 921 kilometers between Harbin in Heilongjiang Province and Dalian in Liaoning Province.

It sounds better than a coal stove in the rear of the car by the restroom.

Replacing steam with head end power to heat passenger cars come to mind? What else has been developed over the last 50 years to help North American freight and passenger trains keep moving in extreme cold?

Eh? Cold? They layup in Minot and send everybody to a hotel.

ROAR

Actually china is building train cars to survive -50 C. They are for interchange service with russian railways to Moscow. Note don’t knock coal stoves the back up heating will be provided by some kind of coal heating.

I wonder what will happen when a HIGH SPEED train hits a snow drift.

POOF!

Ah, but will they be able to withstand temperatures of -40 Fahrenheit?

I will let this sucker question go to those who do not understand ----------

How will the track respond at -40?

About the same . . . [swg]

Also about the same, as it does now . . . [:-^]

What about 263 Kelvin?

What’s up with the four double doors per car? Do they pack people in like sardines? Can they hold an insulated seal that well?

Its called stock photograph, it is used by news media that can’t tell a heavy rail commuter coach from a high-speed coach.

Well if it can withstand - 40 degrees Celsius, then it can withstand -40 degrees Fahrenheit since they are exactly the same.

What about Rankine? This is the US, you know…

Paul,

I like your answer because I understand. Aviation uses Celsius.

Guess not too many people travelled on the C.P.R. west of Moose Jaw in the 1950’s when it was 53 degrees below zero with a nice 45 mph wind.

F -53 = C - 47.2 In today’s terminology that is the equivalent wind chill factor of minus 16,000. ( Hey ! it’s COLD ! !)

China’s first rail to ‘sea of death’ starts operation

On Nov. 29, with the freight train moving slowly from Hami to Lop Nor, the former lake that is known as “the sea of death,” in northwestern Xinjiang Uygur Autonomous Region enters a new era.

It gets deathly cold in N. W. China.

It may take more than new, cold weather resistant rolling stock to entice passengers to make the “Sea of Death” their destination. The photo spread touts freight service to the region.

Frozen passengers and toilets are not a freight concern. What about condensation in air brakes, frozen lubrication, etc.?

Perhaps you meant 233 Kelvin… (419 Rankine)

P.S. Lop Nor? Hmmm, wonder about the fallout from the nuclear testing that occurred there?

LOP NUR, Xinjiang, Nov. 29 (Xinhua) – A train entered Lop Nur in remote northwest China on Thursday, marking the operation of the first railway connecting the sparsely-populated region to the rest of China.

Lop Nur still holds the mystery of the disappearance of Loulan, an ancient Silk Road civilization, in the third century. It was also the site of China’s first atomic bomb test in 1964.

Seals against the cold would need to be extremely efficient. Would these seals also keep unwanted radioactive dust from crew and passengers.
