SomeoneSomewhere:
The well-dressed guy could just be a PR piece - "Joe Bloggs observed the installation of X with his company's new X-inator, which is 3x as fast. Or similar with government ministers or the first/last/half-way point on some project like a new long-distance phone line.
Which would lead me to believe that it's probably electricity or telegraph wires - something significant enough to attract a VIP and photographer.
