From the TR mailbag - yes, I actually do get e-mails from an insatiable public:

A member of the TR community writes me:

I don't know if you're aware CSX just replaced the tracks of the line that parallels US41 in Lutz/Land O Lakes with longer segments having welded joints. Freight doesn't demamd a smooth ride. I don't think CSX would have spent the money unless the fix was in.

-- Maybe, but I wouldn't call it a "fix" per se.  More like, a "realization" or an "ephinany" on the eventuality of Hillsborough County light rail.  Today, tommorow, later, it's coming.  One vote cycle, two, three...it's coming. 

My guess is that if these longer segments have anything to do with future light rail at all, and it is a fix, why, the fix is only to CSX's light rail heart.

The other writes:

From a business standpoint, what types of new businesses do you think will come to the area when this vote is approved and we start gearing up to create our light rail system?

I'm not an expert on commercial migration patterns following the implementation of light rail systems.  However, I am willing to gamble that at least one or two major corporations might eventually want to call downtown Tampa "corporate headquarters".  With an expanding streetcar system, light and high speed rail, and, of course thousands of high rise condos and apartments - Tampa might easily attract them.
