Underground Iron - The building of MTR

I've found a series of documentaries about the building of Hong Kong MTR in Youtube.
Sorry that they are spoken in Cantonese. You may have to guess the meaning...

P.S. Is there any documentaries about SMRT on the web?

There is another version with Cantonese/Chinese subtitiles.
