Did bhagat singh knew about the kakori train robbery in 1927?

The robbery plan was executed by Ram Prasad Bismil, Ashfaqulla Khan, Rajendra Lahiri, Chandrashekhar Azad, Sachindra Bakshi, Keshab Chakravarthy, Manmathnath Gupta, Murari Sharma (fake name of Murari Lal Gupta), Mukundi Lal (Mukundi Lal Gupta) and Banwari Lal.

Hence Bhagat Singh did not know about the robbery.
