Five cows were killed by a train after straying onto to a railway line in Beeston .
Arriva Trains Wales have confirmed the train involved is currently being repaired after the incident.
The cattle were hit by the train coming from Swansea to Chester. It is thought the cows had strayed onto the line.
A vet was requested by the RSPCA and attended the incident immediately.
A spokeswoman from the RSPCA, said: “We were called in the late hours of last Tuesday about an incident involving five cattle injured on a train line.
“Our inspector was able to coordinate communication swiftly between an emergency vet and the rail company to ensure the cows were dealt with as quickly as possible and their suffering was not prolonged.
“Sadly the animals were so badly injured they were put to sleep on veterinary advice to prevent them suffering further.”
A spokesman from Network Rail , Jon Crampton said all cows were removed from the area the next morning after the farmer had been informed.
The spokesman added: “It is believed the cattle got onto the track through a fence, but we cannot not confirm whether the fence was broken or if it had been vandalised.”
The fence was later repaired by Network Rail.
An Arriva Trains Wales spokeswoman said: “The service from Chester to Crewe last Tuesday was cancelled as a result of the accident.
“Please be assured that we look after the cows the best we can.”
