You face the same type of dilemma as the historic railroad lines, excursion type operations.
I talked with some of the operators about this same type of problem- "Not enough people".
One conclusion became unanimous between all the operators and small railroad operators:
They were happy, even though they were doing the job of many, and would rather work for the small outfit that the big monster railroad companies. They have great pride in knowing they all depend on each other, and keep things going, even if at times they are stretched out doing the tasks of many.
The short line railroads have a different personality than the big behemoth railroad corporations. They are tight and operate very efficiently.
Interesting to recognize how the railroaders step up to the plate to keep little railroads going.
Very impressive work ethic.
