Queen fans, I need your help

I recently saw a Queen video on VH1 Classic. It was for a song I'd never heard, and certainly hadn't seen the video before. But I really like it. Anyway, I can't remember the song title at all. The video is from the early 80s and begins with a woman lying on train tracks, blindfolded. The song begins very slowly, then bursts with energy as a train crashes through a brick wall, revealing the band riding the train and performing.

Can anyone help?

Thanks...
