Mr. Gareth Llewellyn:

I do not think a particular system can be lifted and shifted and put into place in respect to MetroLink. All these systems are slightly different. There are many comparisons over here to the Irish context, such as with Crossrail, for example, but that system is also very different. This is a matter of understanding those differences, picking up on the aspects that are likely to be similar and then copying those. There is a requirement, therefore, to look more broadly at metro systems that work and also those that work less well to try to ensure we synthesise the best parts of those examples.
