This bomb was not a bomb that was made to blow apart the train.No it was designed to cause a fire.A fire on a train were people were locked aboard.The windows were barred and the doors bolted.Once the incendiary's detonated people were trapped.A bomb exploding with the force to rip open the train would have caused deaths but would also have made an escape route for many people who who are now dead.This bombing was calculated to cause as much harm as possible.
