Bio-Gas Station Works September 2025

It’s eight years since we introduced our first bio-gas buses and refuelling station. 

Like any other intensely used machinery, regular maintenance and servicing is essential to keep it working and our bio-gas buses fuelled up.

When we fuel the buses, the bio-gas they receive is compressed to maximise the distance the buses can operate each day.

From Monday 8th September 2025, a further compressor in the refuelling station will receive a thorough mid-life service, which will reduce the number of buses we can re-fuel each evening.

To minimise the impact of these works, we will be temporarily:

• Switching some Lime 56, 57, 58 and 59 buses to operate with our Uni4 branded buses
• Using our Uni34 branded buses on any Orange Line service
• Changing buses during the daytime on our Lilac, Orange, Red and Turquoise Lines to refuel them during the day, rather than in the evening – this may mean you will have to change to another bus outside our depot at Parliament Street , on Milton Street or on Canal Street

It may be necessary during these compressor works to allocate a bus that is not the usual colour for your route or one of our generic silver spare buses, so please check the destination on the front of the bus.

Thank you for your understanding and apologies in advance for any inconvenience this may cause.
