This works for me!  I wouldn't even bother drilling a hole.  Polish a 
foot of the top of the rail (if rusted) and lay down copper strap 
holding it down with gravitic pressure from a gravity efficient 
object like a couple of concrete blocks, or a car parked with its 
wheel used for pressure, or hire an 'extra' to stand on 
it.  If you pick the latter, be sure to advise him that if he leaves 
his post during the gig,  you won't expect him to come looking to be 
paid.  Make sure he understands WHY.  Ha, ha.

I've even 'wired' the chassis of several nearby cars and trucks 
together with heavy wire to act as a ground counterpoise once on an 
outdoor Tesla coils show run from a generator.  Worked just fine.

I have plans for a BIG transpotable coil system.  One idea has been 
to mount it on several flatbed railway cars.  The tracks are in my 
opinion an excellent ground counterpoise which come as a free benefit of such a 
scheme.  Before I did this however with a huge machine I would check 
possible effects on nearby railway track monitoring and control 
electronics/electrics.    If you are operating on an abandoned 
section of track you should have no problems.
