Underground Iron – Building the Hong Kong MTR

I’ve previously written a great deal about the MTR network of Hong Kong, but how was it built and constructed? The 1986 documentary titled Underground Iron – The Building of a Railway tells the entire story – originally produced by the Mass Transit Railway Corporation, you can find the complete 30 minute film on YouTube divided up into five sections. Thankfully for us the narration is in English!

  • 2:30 Introduction to the MTR, including train and station footage
  • 6:00 Hong Kong population growth
  • 7:00 History of Chinese refugees entering Hong Kong

Part two covers the early planning for the MTR, up until the opening of the Modified Initial System.

    Need to make a correction on the total cost of the MTR at 1985. Subtitles said “250” but our narrator had said HK$25 Billion

    Hope it helps and thank you for this lovely companion article to the video
