Mr. Tim Gaston:

It is a maximum of a month but it depends on the frequency and scale of what we see. It is a relatively tricky technical process. The file has to be built and tested and then made available to the transport operators who, in turn, put it on the ticketing equipment. We have at least four different types of ticketing equipment in the field. All of the ticketing equipment systems need to be able to handle the electronic file. It is relatively tricky to do but the next generation of equipment we are bringing in will do the overnight update the Chairman suggests, which will be a better way to deal with it, but for now-----
