A video of one youngster's near-miss with a train has been released as part of a new Network Rail safety campaign.
The clip shows the young man sprinting across the railway tracks at Crosskeys in a fruitless attempt to board.
His actions have been condemned by Network Rail Wales Cymru as 'shocking', with a spokesperson saying rail trespass is 'just not a risk worth taking'.
There were 18 fatalities here over the past five years and 27 near-misses last year, with incidents occurring both at stations and along the railway.
The final plans to build a £5.2m new station to serve Energlyn and Churchill Park in Caerphilly County Borough will be unveiled today at a public exhibition.
The new station will be located between Aber and Llanbradach.
Network rail says the new station aims to serve a growing community.
When it's finished it will be operated by Arriva Trains Wales.
The Welsh European Funding Office has helped to fund the scheme, which has been developed jointly by the Welsh Government, Network Rail, Caerphilly County Borough Council, South East Wales Transport Authority (SEWTA) and Arriva Trains Wales (ATW).
Work to clear the railway line between Rhymney and Barry has been completed. It's after trees and debris on the line caused a derailment yesterday morning.
A spokesperson from Network Rail confirmed that all debris was now clear, and the track is now fit for use.
Work is now underway with Arriva Trains Wales to resume normal train services as soon as possible.
Arriva Trains Wales have confirmed train services between Bargoed and Rhymney will be suspended tomorrow to enable Network Rail engineers to clear a landslide which derailed a train this morning.
A replacement bus service and a temporary timetable have been introduced between Bargoed and Rhymney stations, with immediate effect.
The current estimate for the resumption of the normal timetable is from the start of services on Friday 1st February, subject to the successful completion of safety checks.
According to the latest update from Network Rail, 8 passengers and 2 crew members were on board the train that derailed near Bargoed this morning.
There were 3 reported minor injuries, which were treated at the scene.
The emergency services and Network Rail are on site dealing with the incident.
Trains on the Rhymney Valley line are starting and terminating at Bargoed, with a bus service running between Bargoed and Rhymney.
Network Rail says a landslip that caused a train to derail near Bargoed today arose as a result of flooding and snow thaw over the weekend.
This is the train which derailed near Bargoed this morning following a landslip.
Around 10 passengers were aboard the 6.10am Rhymney - Barry Island train when it hit debris resulting from fallen trees between Brithdir and Bargoed.
All passengers have now been safely removed from the train. There are no reported injuries.
