The man ran away through the train carriage, but Craig pursued him and continued to strike him with the bottle until it smashed, leaving Craig holding the broken neck.
The victim’s friend tried to intervene but was also attacked by Craig who punched him seven times before thrusting the broken neck of the bottle into his chest.
He then grabbed one of the victims’ phones and put it in his pocket.
The court heard how Craig had walked down the train before he took off his blood-soaked jumper and replaced it with a clean hoodie from his belongings.
The second victim suffered a stab wound near his heart.
He also had a collapsed lung and a severed artery that resulted in him losing about 15% of his blood.
