Nokia phone series

Nokia's nomenclature can be traced back in 2005, when the Nseries line was introduced. Because of the demands and peak of that line, Nokia again introduced another series of phones named Eseries, made mostly for the enterprise market and to compete with Palm and BlackBerry. In 2009, Nokia dropped their four-digit naming scheme and focused on their two existing lines, with additional two introduced during Nokia World being the Xseries which is for entertainment and music enthusiasts, while Cseries is what Nokia considers their "core" range of products. A Chinese-exclusive range of devices named Tseries was introduced on 13 June 2011. Two more series were introduced at Nokia World 2011 Asha which means "hope" and Lumia which means "light." Other series of phones include the N-Gage,XpressMusic,Navigator series, Prism,Supernova and the fashion-oriented Distinctly Bold and L'Amour Collection.

Nseries

Nokia Nseries is a product family composed exclusively of smartphones and Internet tablets. Mobile devices included in the series include digital multimedia services and other advanced features. The company's flagship products come from this series, and this is where most of Nokia Research Center's technologies and innovations are applied.

Shin-Keisei N800 series

The Shin-Keisei N800 series (新京成N800形) is an electric multiple unit (EMU) train type operated by the private railway operator Shin-Keisei Electric Railway on the Shin-Keisei Line in Chiba Prefecture, Japan, since May 2005.

Design

Built by Nippon Sharyo in Aichi Prefecture, the N800 series design is based on the Keisei 3000 series EMU. Although built as 6-car sets, the units are designed to be lengthened to 8-car sets in the future if required. The N800 series is also intended for use on inter-running services to and from the Keisei Chiba Line. The sets have a maximum speed of 120 km/h (75 mph), but only operate at 85 km/h (55 mph) in service.

Formations

As of 1 April 2015, the fleet consists of three six-car sets based at Kunugiyama Depot with four motored (M) cars and two trailer (T) cars, formed as shown below, with the Mc1 car at the Tsudanuma end.

N700 Series Shinkansen

The N700 series (N700系) is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tokaido and Sanyo 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 25 minutes (5 minutes faster than before).

Operations

N700 series trains gradually replaced 300, 500 and 700 series sets on Nozomi services, and by the end of February 2009, the N700 series were responsible for 74 Nozomi services per day. All Nozomi through runs (over the full route between Tokyo and Hakata) were scheduled to use the N700 series exclusively by 2009. By 2011, all regularly scheduled Nozomi services, including runs limited only to the Tokaido Shinkansen, were operated by the N700 series.
