Hong Kong pop up books by Kit Lau

During my 2016 visit to Hong Kong I dropped into a few local bookshops on the hunt for something a big unusual, and I hit gold – the book ‘Hong Kong Pop-Up’ by illustrator, designer, and paper engineer Kit Lau.

The book cost HK$428 and was sealed up in shrink wrapped plastic, so the purchase was a bit of a gamble, but thankfully the text inside was both in English and Chinese, and the pop up buildings mind blowing.

Six different styles of Hong Kong houses are depicted inside ‘Hong Kong Pop Up‘ – each occupying a double page pop-up spread.

  • Cantonese Tenement (Tong Lau)
  • Shanty Town
  • Resettlement Estate
  • Kowloon Walled City
  • Public Housing Estate
  • Private Condominium Complex

And when I visited Hong Kong in 2019 I stumbled upon a second of his books – 《陸上公共交通》 (‘Hong Kong Ground Public Transportation‘).

Again wrapped in plastic I didn’t get a chance to take a look inside before buying it, but this time my luck ran out – all of the text was in Chinese!

Thankfully the artwork was still worth it – double page spreads on the evolution of the Hong Kong Tramways, KMB buses, local taxis, public light buses, the Kowloon Canton Railway, the MTR, and the Peak Tram.

MTR CKD0A diesel electric locomotives

The list of diesel locomotives in Hong Kong keeps on growing now that I’m digging into the MTR maintenances and work train fleet – the latest entry is the Chinese built CKD0A diesel electric locomotives.

China CNR CKD0A diesel-electric locomotive stabled on a works train at Pat Heung depot

The units were ordered in November 2012:

Following fierce competition, the first independently developed diesel locomotives made on the Chinese mainland have been selected by Hong Kong’s Mass Transit Railway Corp for use in its world-class transit system.

China CNR Co announced last week that it has secured an order worth more than 160 million yuan ($25.7 million) from the MTR for 23 diesel locomotives made with its proprietary technologies.

The designer and builder of the locomotives is a wholly owned CNR subsidiary headquartered in Dalian, Liaoning province.

According to an announcement from the State-owned railway equipment manufacturer, its CKD0A locomotives ordered by the MTR meet the strictest global emission standards and reduce operational noise to less than 70 decibels, lower than the 78-decibel standard on the Chinese mainland.

It can run at 80 kilometers an hour powered by two electric motors and a diesel engine. The design also provides more interior room by eliminating the need for a gearbox, which also improves the locomotive’s reliability.

The driver’s cab has two sets of controllers equipped with computer and cruise control systems.

The CKD0A locomotive is expected to be used in MTR’s rolling stock in addition to subway vehicle rescue.

The contract calls for the first locomotive to be delivered to MTR by March 2014, followed by a 5,000-kilometer test run.

The manufacturer describes them as:

KCRC JMY450 diesel hydraulic locomotives

I’ve written about the Kowloon Canton Railway’s fleet of diesel locomotives before, as well as the MTR’s fleet of battery electric and diesel locomotives, but turns out I was only scratching the surface – on the West Rail line there is another type in use – the Chinese built JMY450 diesel hydraulics.

MTR diesel locomotive stabled on a short works train at Pat Heung Depot

The locomotives were ordered by the KCRC as part of the West Rail line works, with the HK$33 million contract SP-2100 awarded to Shenzhen Sunray Group Co Ltd in June 2000, with the first three locomotives handed over in May 2001.

The first three KCR West Rail diesel locomotives, are completed in Changzhou, Jiangsu, today (Wednesday) and handed over to Kowloon-Canton Railway Corporation (KCRC) by the Deputy Mayor of Changzhou.

The major function of the locomotives is to provide effective and convenient transportation on the newly installed West Rail tracks during the project’s construction stage, enabling engineering staff to install other railway systems along the 30.5 km alignment of West Rail in an effective manner.

The locomotives ready for delivery in Changzhou, China, were handed over to KCRC at a ceremony officiated by Deputy Mayor of Changzhou, Mr Wang Zhengping. The three locomotives will then be delivered to Hong Kong in June. The remaining 11 locomotives to be supplied under the same contract will come in four batches, with the last batch arriving in Hong Kong in April next year.

The on time delivery of the locomotives is of significance to the construction of West Rail as it will facilitate the commencement of the installation work of other railway systems contracts, including telecommunications systems, train control and signalling, as well as traction power supply and overhead line.

“The timely delivery of engineering supplies is critical to opening of West Rail on time and within budget. The West Rail project is progressing well and we are confident that West Rail will commence operation by the end of 2003,” a KCRC spokesman said.

The diesel Locomotives contract, with a value of $33 million, was awarded in June last year. The contractor is Shenzhen Sunray Group Company Limited, which is under the Ministry of Railways of China.

The manufacturer, now known as the Changzhou Kate Mining Machinery Engineering Company, describe the locomotives:

JMY450 hydraulic diesel locomotive can be applied for standard track gauge or for short distance operation, it also can supply traction power for other usage. 14 locomotives of this type have been ordered by Hong Kong Kowloon-Canton Railway corporation (KCRC).

The locomotive is provided with Caterpillar diesel engine with low fuel consumption and electrical fuel ejecting system and the emission of which can comply to EUR II standard, hydraulic reversing, electrical automatic gear shift, low speed control,and faults protecting device. The locomotives can be multiple unit operated, and kept with low noise and pollution which comply to the environmental protection specification of Hong Kong Government.

The Program Logic Controller(PLC) has been applied in electrical system, and the international advanced safety running automatic protecting system (ATC) has been applied in the locomotive.This type of locomotive is kept with good performance, easily operating, high reliability, small volume and long life.

Along with a specification sheet:

14 locomotives #1001-1014 are assigned to the West Rail Line, with an additional two locomotives #1101-1102 to the Ma On Shan Line. Their primary use is shunting trains around maintenance centres, such as this SP1900 set at Pat Heung Depot.

Outlying Islands

A cycling utopia – that is what the outlying islands of Hong Kong are, thanks to their narrow streets and lack of cars.

Main street of Cheung Chau: bikes are the main mode of transport

There were shops hiring bikes to tourists.
