Steelworks opts for cleaner shunters

Porterbrook has purchased three Zephir LOK 16.300 depot shunters.

They will be leased to GB Railfreight and replace hired-in Class 08s for shunting at Celsa Steel Works in Cardiff. Delivery of the first unit is expected in October 2024, and it should immediately go into service.

Although still running on diesel, the LOK 16.300 is a more sustainable option than a Class 08, with an expected fuel efficiency saving of up to 60%. The units also provide depot operational flexibility, as they are capable of operating outside of railway infrastructure on road wheels.

Because it is not currently possible to use battery or electric traction at Celsa Works, due to the duty cycle, the Zephir depot shunters are fitted with Euro 5 engines- the latest in low-emission engine standards for reduced pollution and lower CO₂ emissions. They are also able to run on hydro-treated vegetable oil (HVO bio-diesel).

Currently, four Harry Needle Railroad Company shunters are based at the Celsa Steel Works. These will be returned to their owner after they have been replaced.

GB Railfreight Asset Director Dave Golding said: “We’re pleased to be adding these new industry-leading Zephir shunt locotractors to our fleet.

“Alongside other recent significant investments made by GB Railfreight, including 50 modern JNA-X wagons from Porterbrook, they will help us deliver our target to be net zero by 2050 and help to decarbonise the UK’s supply chains.”

Porterbrook Head of Freight and Route Services Mark Wyborn added: “Porterbrook is committed to investing in rail freight for the long term.

“With over 300 depot shunters currently operating in the UK, and most due for renewal over the next five years, bringing these lower-emission Zephirs under our ownership for GB Railfreight marks a further diversification of our freight fleet, and underlines our dedication to support the sector with affordable, innovative and sustainable rolling stock.”

“We look forward to working with Zephir and our industry partners to continue the roll out of more sustainable assets for depot operations.”
