RENFE Class 446
The 447 series Renfe and Civia trains are a group of electrical units designed to provide effective commuter services.
History
Planning began in the early 1980s and materialized in the prototype Series 445 when commuter services began to take a major role in cities such as Madrid. The units offering these services, mainly 440 series units, became insufficient. It was decided to provide the required facilities for this service, with its short segments and high traveler volume. They were given powerful acceleration at the cost of maximum speed.
Design
The 446 series was an innovative train design Renfe 1989 provides 2400 kW of power, allowing acceleration of 1 m / s² at boot with top speed of 100 km/h. The three cars available to the two ends, both with a driving cab, are motorized and only the middle one is a trailer. Each car has 3 pairs of double doors for quick entry and exit of travelers. One of the major drawbacks of these units, which cost them the nickname dodotis is that originally they did not have toilets in the cars.
Outwardly look similar to the Renfe Class 447 design except for the letters of the car numbers, because in the 446 series the letters M or R are blank and the 447 series this letter is in yellow and has a greater overall width of 9 cm. These two units have changed their aesthetics over their lifetime. The "C" characteristic of 1992 and changing the red/violet colors and the appearance of the word Renfe after segregation Adif. Taking advantage of these recent changes also security enhancements were added in signaling systems of closing doors as sound and indicator lights. They can circulate coupled normal service units series 447 with some limitations in traction and brake. Of the 170 units delivered, 25 were remote or deregistered, including those affected in attacks of March 11, 2004. You can find these units circulating nuclei Madrid, Seville, San Sebastián, Santander and Bilbao soliendo make their services in lines where the distance between stations is 1-2 kilometers or even less.
