Sir Alexander, named after by-then governor of Hong Kong in 1955,
Alexander Grantham, was retired in 1997 and donated and preserved in
Hong Kong Railway Museum in 2004. • 52–55 were retired in June 2004 (however 55 did see limited shunting use for a short while) and re-sold to
Chicago Freight Car Leasing Australia in October 2005, arriving that December and reentering service in late 2006-early 2007 as TL152–TL155. Before being loaded on the ship to Australia, the locomotives had their nameplates removed and KCR logos painted over. • TL152 (originally 52
Lady Maurine) sold to K&AB Rail c. 2014, to SCT 2020, now used as shunter at the Wimmera Intermodal Freight Terminal at
Dooen. • TL153 (originally 53
H.P. Winslow) sold to the Dalby Machinery Centre in
Dalby, west of Toowoomba in Queensland, as a static exhibit. On display at the entrance to the centre. • TL154 (originally 54
R. Baker) owned by ALARC, stored at Tailem Bend. No longer operable due to copper thieves, used as source of spare parts for TL155. • TL155 (originally 55
R.D. Walker) owned by ALARC. Restored in 2020, hired out to SCT. • The names of the locomotives were originally painted on the valance underneath the long hood catwalks, however they were replaced with cast nameplates in the late 1980s. All locomotives apart from 51 lost their names when sold to CFCLA. • 51 and 52 were built with Clyde's stock buffers-and-chain couplers, as well as the number board/headlight fixture flush with the top of the hoods. These were replaced with automatic couplers sometime after arrival in Hong Kong. 53 to 55 were built with slightly lowered number board fixtures. • In 1996, the locomotives were heavily modified, with large air conditioning units mounted to the cab, diesel generators installed in the No. 2 end to power them (which involved slightly lengthening the long end hood under the number boards) and full-length handrails. These modifications were retained on 51 at preservation (minus the air conditioner), to illustrate the changes the locomotives had gone through during service in Hong Kong. Further modifications made to the locomotives in CFCLA service included installation of reinforced side windows, slightly widening the steps on the front left and rear right sides of the units and adding an extra rung to the modified steps. The original Hong Kong air conditioners had been removed when retired from KCR service, but new, smaller ones were fitted by CFCLA. The locomotives had the stock EMD exhaust pipes replaced with larger twin exhausts in the 1950s after arrival in Hong Kong, which were replaced with box-like exhaust silencers in the 1980s. • As delivered, the locomotives wore a green livery, with a silver upper section and the numbers painted on the cabsides and ends. In the 1980s, this was changed to a grey livery, with the cabside numbers relocated to the hood sides and replaced with a KCR logo, but retaining the silver upper section. In 1996, 54 was painted in a blue livery with green valances. 52, 53 and 55 would soon after be repainted in a red livery with blue valances, which all other operating KCR diesels were soon repainted into. 51 did not receive this livery, and in 2003 was repainted into a rough approximation of its original livery based on the 1980s livery.
