Hi Steve, the project is not necessarily folly. Trying to bring it home for five thousand is the issue.
I would guess, without looking at the location that a ten to fifteen K price mark would be real for parts, product and labor.
If they are going to run two trains at once they should have four engines on stand by.
It would be wise to project an engine rebuild about once a month. If you use a cheap starter set like the Polar express the engine pilot trucks front and rear would have to be rebuilt every fifty hours of run time or so.
I really don't think five thosand dollars a year for maintenance is tha far off the mark. We tend to forget how many man hours go into keeping our trains running over the course of a year, that is why we call it a hobby.
Even at ten dollars an hour for labor at about an average of four hours a week comes to forty dollars a week. Times that by fifty-two weeks a year and you come up with a number of over two thousand dollars.
Now you have to add in repair and replacment cost and we are getting real close to 5K.
Remember, the above numbers are predicated on finding a trained maintenance person to work for ten bucks an hour. A counter person is one thing but climbing up on that ladder dusting, vacuuming, adjusting the display as it expands and contracts through the seasonal changes is another issue all together.
When ever you place a bid on anything double the cost of material and then add another twenty-five percent on top of that. This is only a rule of thumb but it is better to walk away rejected then a bum who could not get the job done.
