If your backs and feet and knees hurt too much you could go full-prototype and abandon the line.  Pull up the rails, cover the roadbed with weeds, let the local volunteer fire department burn a depot or elevator for practice (Heather would love watch that!), etc.  Then the old farts could eat lunch then go downstairs and reminisce about the "good old days" when Death Valley Scotty ran the varnish across the Alma Branch at 85 mph or whatever delusions old farts come up with....

Might I suggest a bathroom break after turning the train at Alma.  And some of those interlocking foam floor mats for the area around Burlingame because folks spend a lot of time there standing around scratching their heads....
