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 Tōkaidō and San'yō Shinkansen lines since 2007, and is 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 (8,202 ft) radius curves that previously had a maximum speed of 255 km/h (158 mph). Another feature of the N700 is that it accelerates more quickly than the older 700 series Shinkansen trains, with a maximum acceleration rate of 2.6 km/h/s (0.72 m/s2). This enables it to reach 270 km/h (170 mph) in only three minutes. Further advancements led to the development of the N700A, an incremental evolution of the N700. N700A trains can reach 285 km/h (177 mph) on 3,000 m (9,843 ft) curves, allowing the maximum operating speed on the Tōkaidō Shinkansen to be raised to 285 km/h (177 mph). All N700 series sets have been retrofitted with most of the improvements added to the N700A series, and are now classified as "N700A".
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 the fastest service.

Fate
HMS TEAZER returned to UK post WWII in 1946 and was placed in Reserve at Devonport. She was selected for full conversion to an Anti-Submarine Frigate in 1952 but this was later changed because of the costs involved. Instead a limited conversion (Type 16 Anti-Submarine Frigate) was approved and on completion by 1956 was recommissioned for service in the 2nd Training squadron.
She was placed on the Disposal List in 1965 and sold to BISCO for breaking-up at Dalmuir where she arrived in tow on 7th August that year.
Vessel allocated the following pennant numbers:
R23……………….1943 until Sept 1948
D23………………Sept 1948 until 1951
F23……………….1952 until 1965 (as Type 16 Frigate)
