5. Will the Minister make a statement on the provision of rolling stock on the Rhymney to Cardiff rail line? OAQ53416

Yes. Transport for Wales anticipates new rolling stock to be provided by May 2019, if not earlier.

When James Price gave evidence to the Economy, Infrastructure and Skills Committee, he indicated that there would be additional rolling stock by May this year; if not by May, then possibly by March. Peak time, particularly coming home at peak time, on the Cardiff to Rhymney line is terrible. Seating is very hard to come by. This improvement in March/May would be very welcome. Can you provide an update on how progress is being made, what extra seats would likely be provided, how many extra seats are likely to be provided, and what further progress would be made by the end of this year? 

Yes. Can I thank the Member for his question, and just say how much I value the pressure that the Member has placed on me and Transport for Wales to ensure that his constituents get the best possible services through Transport for Wales? They are requiring five class 769 trains for the Rhymney line. I said that we aim to have them on the tracks by May of this year, but it's my hope that we could see them delivered next month. I think it's important to reflect on the fact that capacity on the network at the moment is severely stretched, and so I'm pleased to say that capacity will be increased from 212 to 292 seats on those trains that are going to be brought into use. 

I believe the Minister and Transport for Wales have suggested we may in due course see tri-mode trains on this line, with both overhead electric, diesel and battery operation. How firm is that policy, because I'm aware that some concerns have been raised as to the added weight of the battery and, despite the advantage of that for coming through the Caerphilly tunnel, whether that added weight elsewhere in operation may make the trains overall less efficient? Not everyone is agreed that this is necessarily the right technical solution, given that we haven't really seen it elsewhere in the world.   

They are tried and tested, the tri-mode trains, and they will be used on the Rhymney line from 2023. They use a mix of diesel power, overhead electric and also battery power. In terms of battery power, huge strides are being made in terms of the development of new lighter, smaller batteries, and I think, whilst there is some disagreement amongst experts at the moment, there is recognition that, as technology advances, the weight of battery units in trains and in cars will go on falling and, therefore, those units and vehicles will become more efficient and be able to cope with more passengers as well.

The whole point of our procurement exercise was that it was mode-agnostic. We were driven by the objectives, and the objective was to ensure that we could deliver as many services as frequently as possible, carrying as many people as possible, and the market assessed what would be best for each and every line, and determined that on the Rhymney line a tri-mode solution was the most appropriate.
