On tracks that London Underground share with National Rail third-rail stock (the Bakerloo and District lines both have such sections), the centre rail is connected to the running rails, allowing both types of train to operate, at a compromise voltage of 660 V. Underground trains pass from one section to the other at speed; lineside electrical connections and resistances separate the two types of supply. These routes were originally solely electrified on the four-rail system by the LNWR before National Rail trains were rewired to their standard three-rail system to simplify rolling stock use.
What is the voltage shared two types of trains UK railroad system?
660 V

After the establishment of Hampshire County Council, following the act in 1888, Southampton became a county borough within the county of Hampshire, which meant that it had many features of a county, but governance was now shared between the Corporation in Southampton and the new county council. There is a great source of confusion in the fact that the ancient shire county, along with its associated assizes, was known as the County of Southampton or Southamptonshire. This was officially changed to Hampshire in 1959 although the county had been commonly known as Hampshire or Hantscire for centuries. Southampton became a non-metropolitan district in 1974.
What year was the county of Hampshire officially named?
1959

Men's rhythmic gymnastics is related to both Men's artistic gymnastics and wushu martial arts. It emerged in Japan from stick gymnastics. Stick gymnastics has been taught and performed for many years with the aim of improving physical strength and health. Male athletes are judged on some of the same physical abilities and skills as their female counterparts, such as hand/body-eye co-ordination, but tumbling, strength, power, and martial arts skills are the main focus, as opposed to flexibility and dance in women's rhythmic gymnastics. There are a growing number of participants, competing alone and on a team; it is most popular in Asia, especially in Japan where high school and university teams compete fiercely. As of 2002[update], there were 1000 men's rhythmic gymnasts in Japan.[citation needed]
