Good Afternoon Dan 

Thank you very much for your question in regards to the Gas buses. 

The Gas Buses are filled by a similar method as the remaining diesel buses in our fleet and we receive delivers three times a week of LNG. As the fleet of gas buses has grown the current facility we have for gas storage been left at minimal levels on a Monday morning before the first delivery of the week. To reduce the risk of fully depleting our gas facility we have decided as a temporary measure to withdraw them from Sunday services. 

The Company has invested in a new fuelling system for the Gas buses in order to be able to connect a pump directly to the main gas supply, once this is complete we will no longer need delivers of gas each week and you will then see Gas buses on the road each day again. The system is currently being set up and due to be completed by the end of August. 

I hope this answers your question and if you require anything further please do not hesitate to contact me. 

Kind Regards,
