Vivarail battery electric train. Vivarail have produced the Class 230 train which is converted from redundant London Underground D-Stock trains. A demonstrator unit, the two-car 230002, was fitted for diesel-electric- battery power. Vivarail developed a fast charger giving a 100 mi (160 km) range with a 10 minutes recharging time. [1]
The 3.2-litre, five-cylinder diesel engines are manufactured by Ford in South Africa. [16] Lithium Werks (formerly Valance) is the supplier of the battery rafts, while the electronic power control systems are produced by Strukton Rail. The three-phase AC traction motors are sourced from specialist Traktionssysteme Austria. Reportedly, the ...
IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging. It consists of three phases (or stages), to be executed by a battery charger. The three phases are: I-phase (constant electric current), Uo-phase (constant over-voltage), and U-phase ...
A trial by Great Western Railway (GWR) for rapid-charging battery trains is underway, as part of plans to phase out diesel engines.. The initiative was launched in February 2022, with the trials ...
The first prototype unit operating during the 2017 Rail Live event. A prototype was produced for testing and accreditation in August 2015. [4] [5] The initial prototype D-Train was built as a three-car diesel-electric unit, which was completed in the summer of 2016, following which it underwent a programme of main-line testing, with the intention that it be used on a year-long trial service on ...
Vivarail's main project was the conversion of retired London Underground D78 Stock into two new classes for National Rail services. It was led by former Chiltern Railways chairman Adrian Shooter; the American Railroad Development Corporation was a shareholder. [1] [2] [3] In November 2022, the company entered into administration.
Converted from three-phase 6600 V 25 Hz in 1927, dismantled 1956 United States: Colorado: Denver and Intermountain Railroad: dismantled c. 1953 [35] 12 kV: 16 + 2 ⁄ 3 Hz France: lines in Pyrenees: Chemin de fer du Midi: most converted to 1,500 V 1922–23; Villefranche-Perpignan diesel 1971, then 1,500 V 1984 12 kV: 25 Hz United States
To accelerate the charging time and provide continuous charging, an intelligent charger attempts to detect the state of charge and condition of the battery and applies a three-stage charging scheme. The following description assumes a sealed lead–acid traction battery at 25 °C (77 °F).
