With regard to Colombia, Chile, and Peru, at this point in time we don't have a significant presence. We have people on the ground because we're looking at opportunities in rail and also aerospace. We have some prospective customers in those countries.
In rail, as I mentioned briefly in my opening remarks, we're looking at opportunities to supply signalling systems and train control technologies for the metro lines that they want to expand in Chile and Peru. For instance, Santiago has a number of metro line projects that we're currently looking at.
In Colombia, as I also mentioned, there are opportunities for metro and light-rail train projects, for which we may have an opportunity to be a supplier of either the rolling stock or of systems for these infrastructure projects. There are also refurbishment opportunities, existing cars that we can refurbish.
With respect to whether we could invest in those countries, we have invested in Mexico for a number of reasons. On the rail side, we acquired many years ago an existing company that manufactured rolling stock, and that is what we're doing. In aerospace, we invested in Mexico because we were, to put it simply, quite attracted by the investment environment and also by the aerospace cluster that they were ready to establish in Mexico, with support for training and for putting educational facilities in place as well to make sure that there's a supply of a specialized workforce able to grow and support our investment.
I would say that the business model is different between aerospace and rail. With rail, the projects tend to be longer term. When we get involved in a rail project, we become almost an investor, because we have to send engineers, often for a number of years, to work on projects. There might be requirements sometimes to localize, or some offset requirements.
If the size of the market justifies the investment, as in Brazil, and we see a good pipeline of projects going forward for the country—the market itself, but also the region—we may consider localizing production, to some extent.
