Ten passengers and two staff were on the train, but there were no injuries.
Network Rail said the incident happened just before 06:30 GMT on Wednesday between Brithdir and Bargoed stations.
Services between Rhymney and Bargoed have been replaced with buses while a recovery operation and safety investigation is carried out.
"This was a minor derailment, where one bogey has come away from the track," said an Arriva Train Wales spokesperson.
"There was a small number of passengers onboard, and they are all perfectly okay."
The spokesperson said the service had been the first of the day from Rhymney to Barry in the Vale of Glamorgan.
Investigation underway
"We understand that because of the heavy rain there was a minor landslip that has brought the tree and foliage onto the track," explained the Arriva Trains spokesperson.
Trains have now started running again from Bargoed towards Cardiff, while buses are replacing services between Rhymney and Bargoed.
Network Rail, which is responsible for operating rail tracks, said it could be sometime before the line fully reopens.
"The train has to be moved, and that will depend on any damage to it or the tracks. The tracks will then have to be inspected and any repairs carried out," said a spokesperson for Network Rail.
"It is too early to say how long that will take."
