'A number of factors led to 2015 Denver train crash'
Last year, a Metro Express train collided with a MetroPlus train in the south of Johannesburg.
PRETORIA - An investigation has found that a combination of factors, including speed and an inability to communicate, contributed to the Denver Train Station crash, which left one person dead and 240 injured.
In April last year, a Metro Express train collided with the back of a MetroPlus train that had stopped at the Denver Train Station in the south of Johannesburg.

Transport Minister Dipuo Peters and the railway safety regulator released the findings of the investigation in Pretoria today.
The regulator's investigation found that the driver of the express train was speeding and failed to adhere to two warning signals.
The Metro train had stopped at the station because the driver could not see the signal light and he couldn't contact the control centre because a power supply interruption meant the radio system was not working.
Prasa's Mosengwa Mofi says they started improving safety measures soon after the crash.
"Some of the underlying factors such as not having back up power supply is something we have put in place, but also in terms of the signal aspects, we are currently rolling out LED lights in all our signalling installations."
He says the agency takes accountability and safety seriously and will ensure all recommendations are implemented.
