amazing different types of CNC machines 

 

Computerized Numerical Control (CNC) Machining is a method used to perform a wide range of manufacturing tasks, which are all carried out by computerized devices. With the help of Computer Aided Design (CAD) and Computer Aided Machining (CAM) in the late 1970s, CNC machines replaced the old-school manual machines.
CNC – Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine.

 The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines

As a rule, there are 10 or 20 train cars forming the train set as well as several coach classes to choose from: 2nd Class (Standard) usually has seats arranged 2 by 2, whereas the KTX 

 

 

High speed rail the major mode of transport in China

High speed rail the major mode of transport in China 

The high-speed service is mainly operated by China Railway High-speed. HSR developed rapidly in China over the past 15 years thanks to generous funding from the Chinese government. With ridership exceeding 1.44 billion in 2016, China's HSR service was the most heavily used in the world. In 2016, the network is the longest in the world and accounted for about two-thirds of the world's high-speed rail tracks and operated with 2,595 high-speed trains, accounting for about 60 percent of all global high-speed trains.needs update

Japanese Bullet train Passing in parallel The N700 series (N700系 Enu nanahyaku-kei) is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR-West for use on the Tokaido and San'yō Shinkansen lines since 2007, and also operated by JR Kyushu on the Kyushu Shinkansen line.

 N700 series trains have a maximum speed of 300 km/h (186 mph), and tilting of up to one degree allows the trains to maintain 270 km/h (168 mph) even on 2,500 m (8,200 ft) radius curves that previously had a maximum speed of 255 km/h (158 mph). Another feature of the N700 is that it accelerates quicker than other shinkansen trains, with a maximum acceleration rate of 2.6 km/h/s.

This enables it to reach 270 km/h (170 mph) in only three minutes. Because of these improvements, trains can travel between Tokyo and Osaka on a Nozomi run in as little as 2 hours and 22 minutes on a fastest service (8 minutes faster than before). 

 

 

 

 

Train track in bad condition make so much noise

Train track in bad condition make so much noise 

 

 

Transport, including railways, is one of the main sources of noise, with a particularly strong negative impact on the environment, and on the health of children and adults. Train noise depends on the types of trains, track-type driving, driving speed and driving mode. Noise levels also depends on the rotation of the wheels on the track and on the short track wheel beats connections.. 

 

Train track in bad condition make so much noise

 The results of measurements showed that urban rail noise analyzed in the residential area is a serious problem, which needs addressing various organizational and technical measures... It was found that the rail transport caused equivalent and maximum noise levels of 20 m from the railway in the residential area were approximately 20 dB above the permissible noise levels. 

 

Train track in bad condition make so much noise

During the day, noise tests exceeded the permissible levels in nearly 80 % of all measurements. At night, the noise levels exceeded allowances on each of all noise level measurements. Statistical analysis of the results showed that the noise level is dependent on the train type and distance to the railway track.

 This is the one I encountered in Xi’an, a city of 8.7 million people. It had high ceilings, futuristic architecture, and nicely spaced gates for the platforms. It's little surprise. The nationwide system covers 15,500 miles, a figure made more impressive when you consider the first line was built in 2008 for the Beijing Olympics.
