Bank Robbers Trapped in Flooded Subway?

[bgadow]

Saw this on TV one afternoon in the early/mid 80s, back when "regular" tv stations used to do such things. I've long wondered about the film, what the title was, etc. What I remember: 2 streetwise women work for this guy who has them plant a bomb at a bank. I don't think they knew it was a bomb. He warns them not to take the subway home, but they do. When the bomb blows it cause a breach that floods the tunnel. Somebody dies on the "third rail" and the kindly engineer, an older black man, also dies. Don't remember what happened after that. Quite possibly I watched this on a GE 'KC' chassis color set with cataracts. Does this jog any memories?
