There was a time in my career that I'd have said yes, the developers make the most sense as they are the only ones that really understand the process. But now I know that's exactly the problem with having developers doing the installs. For a production system you need to have a well defined process that produces repeatable results. The only way to ensure that is to have a separation of duties, whether it's an administrator that's being intelligent hands for a human-readable script, or is simply kicking off a developer provided computer readable script.
I spent a month there a year ago; the trains are the best. Anywhere my wife and I wanted to go, there were two trains an hour. We never worried about transportation on the far end; you can nearly always find a cab even in the sticks. TfL's London Transport Museum is off the beaten path, and has a fair amount of cool stuff.
