Glad to. The laws have since changed in several of the states in which I operated [IN,KY,TN & MO] both for the good and the bad. I originally set up with a charter as a railway express company, in response to an announced AMTRAK route relocation that never came to pass. Instead, I picked up contracts for moving drug shipments from a nearby Pfizer plant, now relocated offshore.
At that time a Ry Express company could still be chartered in IN at the rate of #10 for each county in which you operated; mine was the last company so chartered before the law was changed, now only gold transportation qualifies for Express Company incorporation in the Hoosier state.
But there are similar vacuums elsewhere, [ see Dave Blatter's obit *here*] and federal law supersedes state regs when the feds take the trouble to enforce it. And some of them are quite useful, particularly when moving deliveries for the FedGov.
And whether you go with the traditional armored box on a truck chassis [*tinbox* in the trade] or *plain wrapper* ex-cop cars or other Kevlar-armored sedans common with those who primarily service ATMs, you'll want to look into joining up with the Independent Armored Car Owners Association.
Hey wait! That sounds like work!
I just want the machine guns.
