Train death dad-of-two had debts of pounds 28,000.
At the inquest into his death yesterday a jury heard Mr Blacker, a divorcee and retired supervisor for Lloyd's Bank, had a pounds 28,000 debt and may have been facing eviction from his rented Duke Street home.
Michael Ford, the driver of the train, said he saw Mr Blacker walk down to the tracks as his train was approaching the platform.
"The gentleman was walking down the ramp of the platform and towards me. He was walking on the side of the tracks. I blew my horn, I looked away to hit the emergency brake and when I looked back up he was lying in the middle of the tracks."
Mr Ford was unable to say if Mr Blacker had walked on to the tracks or fallen as the train approached.
In a statement from Alison Blacker, his ex-wife, the court heard he had a drinking problem and had become estranged from his daughter, aged 20, and son, aged 18.
She said Mr Blacker could suffer from low moods but was not clinically depressed.
"He never talked about self harm or suicide. I would not say he was capable of taking his own life," she added.
