The CR300AF Fuxing is one of the Fuxing electric multiple unit developed for China Railway High-speed network. [1] It was ordered by China Railway from CRRC Qingdao Sifang.

Development

The CR300 series Fuxing Hao EMUs (250 km/h class) are the third class of Fuxing Hao EMUs, following the CR400 series (350 km/h class) and CR200J series (160 km/h class).

In early 2018, design reviews for the CR300 series Fuxing Hao EMUs began. [2] By the end of September 2018, the CR300AF-0001 prototype was manufactured and rolled off the production line. On October 17, the 0001 prototype was transferred without power to the Beijing National Railway Test Centre for testing. On December 7, unit 0001 was transferred to Chengdu railway station. On December 13, unit 0001 began test runs on the Chengdu–Guiyang High-Speed Railway section between Leshan railway station and Xingwen railway station, which was undergoing joint commissioning and testing.

On November 14, 2019, the National Railway Administration approved CRRC Sifang for mass production of the CR300AF type EMU.

On March 10, 2020, the National Railway Administration also officially approved CRRC Nanjing Puzhen for mass production of the CR300AF type EMU, marking the first time the company obtained qualification to produce high-speed trains. [3]

On November 24, 2020, China Railway Nanning Group announced that 5 CR300AF units arriving by year-end would assist with the 2021 Spring Festival travel season. [4]

On December 25, 2020, the CR300AF began passenger operations, with the inaugural train departing from Kunming South railway station via the Kunming–Chuxiong–Dali railway to Dali railway station. [5]

On April 30, 2021, the CR300AF began operating on the Hainan Ring High-Speed Railway. [6]

The CR300AF features a new front end design, with a shorter nose compared to the CR400AF. As it does not include business class seating, the two auxiliary windows on the front of the CR400AF's driver's cab have been removed, and the side windows have been raised and changed from narrow trapezoidal windows to rhomboid windows.

In terms of livery, the production CR300AF, like the CR300BF, uses sky blue as its base color. Unlike the CR300BF, which is nicknamed "Blue Warm Man", the CR300AF's appearance, resembling a cool and elegant beauty, has earned it the nickname "Blue Sister" among railway enthusiasts. [7] The red stripe on the front and sides of the leading car and the black window livery design are consistent with the CR400AF. During factory testing, the prototype CR300AF temporarily used a silver-grey base color similar to the CR400AF, and the red stripe design on the side of the leading car also differed from the production livery.

Power configuration

The CR300AF adopts an 8-car formation with a 4M4T (4 motor cars, 4 trailer cars) power configuration, consisting of two basic power units. Cars 02, 04, 05, and 07 are motor cars, while cars 01, 03, 06, and 08 are trailer cars.

Key equipment

Traction system

The traction motors and traction inverters of the CR300AF are manufactured by CRRC Zhuzhou Electric and CRRC Times Electric respectively. The rectification and inversion stages utilize a high-power IGBT-based AC-DC-AC traction system. By increasing the intermediate DC link voltage, efficiency is improved, losses are reduced, motor control characteristics are enhanced, and traction output power per unit mass is increased. The system fully utilizes component performance to significantly increase electric braking power based on traction power. Phase-shifting technology is used to effectively control harmonics, ensure the quality of regenerative energy recovery, and reduce overall energy consumption.

The CR300AF produces less magnetic excitation noise during acceleration and braking compared to the CRH2 series EMUs. Its magnetic excitation noise is closer to previous Times Electric products, rather than the distinct low-pitched magnetic noise emitted by older Hitachi VVVF systems.

Pantograph and power supply system

The CR300AF is equipped with pantographs on cars 3 and 6. One pantograph is used during normal operation, while two are used for multiple-unit operation.

Interior

The CR300AF trainset comprises one first-class car and seven second-class cars, with a total capacity of 613 passengers. Compared to the Harmony series EMUs, the seat pitch is more spacious. The entire train is equipped with Wi-Fi antennas, providing wireless internet service, and features accessible restrooms, USB power outlets, large luggage racks, luggage rack indicator lights, and washroom shelves. Compared to the CR400AF, the second-class seat fabric has been changed from beige stripes to blue geometric patterns. The train also includes a seat information display system, indicating seat numbers and reservation status. [8] [9]

Additionally, for the CR300AF Hainan Eastern Ring customized version operating on the Hainan Eastern Ring High-Speed Railway since February 2021, the second-class car capacity remains the same as the production model. However, the first-class car (Car 01) has been converted into a combined first-class/business class car, similar to those on the CR400AF and CR400BF. The capacity of Car 01 has been adjusted from the original 48 seats to 33 seats (5 business class + 28 first class), reducing the total train capacity from 613 to 598 passengers. [10]

Allocation

As of January 2021, 64 CR300AF Fuxing Hao EMUs have been delivered.
