Following the opening of the new diesel locomotive running shed at Lo Wu in 2014, the facility at Hung Hom was taken out of use. The 無人之境 / Abandoned HK group of urban explorers paid a visit to it shortly before demolition.
You can see the full series of photos on the 無人之境 / Abandoned HK Facebook page.
‘Tea Mori’ on Flickr also paid a visit to the abandoned depot in 2014.
My memory isn’t to great over thirty years later but what I can remember is there being a Chinese Railways diesel locomotive assigned to Hung Hom, saw it there a couple of times and even once saw it heading north over Waterloo Road.

I think you may refer to the class DF2 diesel locomotive leased by KCR in the early 1980s?
The hired DF2 diesel gets a mention in this film on the KCR pre-electrification:
