A survivor of the bombings on the rail system in India's largest city says a blast damaged his train car so badly that he was amazed anyone got out in one piece.

Santosh Raphod was on his way home from work during Tuesday's rush hour in Mumbai when the carriage he was riding in exploded, he toldCBC News on Wednesday.

It was one of eight blasts on the western port's commuter train system that killedat least 200people and injured more than700 others.

'I couldn't hear the sound, I was very close to the bomb.After a few seconds, everything was blacked out. All dust was all over us.' -Santosh Raphod, who was about three metresfrom an explodingbomb

Train carriages alongthe city's widely used western rail line were ripped open between 6:30 p.m. and 7 p.m. local time. No one has claimed responsibility for the attacks.

Raphod said he was standing about three metresfrom the bomb when it exploded.

"I couldn't hear the sound, I was very close to the bomb," he said. "After a few seconds, everything was blacked out. All dust was all over us."

Raphod said he realized a few seconds later that he was injured.

"My head was hit with a splinter. I was bleeding," he said.

Bleeding from head, he stumbled out

He said he didn't even realize he had been knocked down until another man told him. The pair made their way out of the train onto the tracks.

Raphod said he was stunned by the state of the train car.

"It was totally broken down. I was surprised to see how people came out in one piece because the train was so badly damaged," he said.

There was chaos in the neighbouring carriage, which was a ladies first-class compartment. Mumbai, likea number of other major cities in the world, offers women-only cars in response to complaints of groping and sexual harassment.

"There was panic. They were crying all around," said Raphod.

He received several stitches in his head and remained in hospital three hours for observation. Raphod said he stayed home from work Wednesday because of "terrible" head pain.

Mumbai needs rail system 'lifeline'

Raphod said he is concerned about future attacks, but said the commuter rail system is crucial to Mumbai because it is fast and inexpensive.

Mumbai's commuter rail line, whichcarries more than six million passengerseach day, is among the most crowded rail systems in the world.

"There is no alternative for [Mumbai] people," said Raphod. "It is the lifeline of [Mumbai]."

India's financial and entertainment capital, Mumbai's name was officially changed from Bombay in 1995.
