β€˜The Trains Are Slower Because They Slowed the Trains Down’

β€˜The Trains Are Slower Because They Slowed the Trains Down’

There has been a lot of talk about improving safety, to avoid preventable deaths in all sectors of American life these days. But saving lives has a real cost -- often it means slowing down business, and making it more expensive to get things done. Safety is important, but so getting through the business of every day life. It's important that weight the safety benefits against the cost of saving a few lives. A preventable death of a loved one is always tragic, but sometimes it's better to let a few people die preventable deaths, for the betterment of society.

"Benjamin Kabak, who writes the subway-focused blog Second Ave. Sagas and has been one of the few transit advocates raising concerns about the subway’s slowdown, agrees with the operator’s assessment. β€œI don’t think they’re wrong in citing safety,” Kabak says of MTA management, β€œbut I think there’s a question as to whether their reaction is commensurate to the problem.” He doesn’t see a safety benefit to the vast majority of timers installed around the system. As an example, Kabak recently noticed the 6 train crawling between 51st Street and Grand Central on a regular basis. He suspects a timer has recently been installed there."

Is it true that train diesel engines are always kept running and not completely shut down? If yes, why?

Is it true that train diesel engines are always kept running and not completely shut down? If yes, why?

This is actually not surprising when you think about it. Most large engines are left running even when their power output is unneeded as they have long periods of time to start from a cold start. Most power plants take somewhere between quarter to half a day to get up to speed, some coal or nuclear plants take multiple days to reach speed. Cold starts are rough on engines, large engines take a lot of time to evenly heat the block and fully lubricate the engine before they can be loaded.

How to Drive a Trabant

The COMMUNISTS made the BEST CARS!

" In a rare informational video, I show you how to steal my Trabant if you happen to find it with the keys inside. Typically, I don't let this happen, but you'll be prepared to make off in my communist box if I do. I'm not worried. You won't exactly outrun the police in a Trabant. Of course, all of these instructions assume you already know how to drive a car with a manual. I'm not letting you near my Trabant if you don't already know that."

Why don’t electric cars have transmissions?

Why don’t electric cars have transmissions?

"Electric motors do not have the same limitations as internal combustion engines. They produce the same amount of torque at near zero as they do at high rpm. Turning slower does not use less battery power. The load is what determines how much power the car uses. Eliminating a gearbox also has the advantage of eliminating weight and gearbox losses, which makes the load smaller. And finally, doing so conforms to a long standing wisdom that engineers often forget. It called the KISS principle."

How To Tumble With Care When It Gets Slippery Outside

How To Tumble With Care When It Gets Slippery Outside

"It's that time of year when a simple walk down the street can be a treacherous undertaking because of the icy sidewalks. Emergency rooms in the U.S. treat more people injured in falls than for any other kind of injury, according to the Agency for Healthcare Research and Quality. The agency estimates that falls account for more than a third of all injury-related ER visits. Even though most of those injuries happen to older people, falls happen at any age and can cause serious injury. If you know you're about to slip and fall on the ice, there may be no way to prevent it, but there are things you can do reduce your risk of serious injury."
