I’ve written about MTR’s fleet of maintenance and work trains before, but it turns out there is one class of diesel electric locomotives I’ve missed – the JMD1200FX units used on the Hong Kong Express Rail Link.
The TrainNets.com website (Chinese language) has further details on the JMD1200FX diesel electric locomotives.
The JMD1200FX locomotive is manufactured by Jiangsu Jinchuang Vehicle Co., Ltd. They are used by the MTR Corporation on the Hong Kong section of the Guangzhou-Shenzhen-Hong Kong high-speed railway and are based at the Shek Kong Depot. They are numbered 19001-19003.
The bo-bo locomotives have a top speed is 80km/h and can be operated in multiple unit. Starting traction is 269kN and continuous traction is 182kN.
The locomotive features a CAT C32 V12-cylinder diesel engine, with a power of 895kW (1200 horsepower), coupled to a JF205F synchronous main generator produced by China CNR Yongji New Speed Motor Co., Ltd. Overall weight is 80 tonnes.
A single locomotive can pull a 8-carriage high-speed EMUs (empty weight 490t) or double-head a 16-carriage high-speed EMUs (empty weight 980t) on a 3% gradient at 10km/h.
It can also pull a 8-car high-speed EMU (full load 536t) or double-head a 16-car high-speed EMU (full load 1072t) on a 2% gradient at 15km/h.
On level track it can also pull a 8-car high-speed EMU (full load 536t) or double-head a 16-car high-speed EMU (full load 1072t) up to 60km/h.
