To my knowledge (not a definite source, but I am an engineering consultant in a related field):
There's a difference between the daily checks that parks perform and the less frequent (annual or less) checks. I think Norwegian Coasterfan is getting at that point. To my knowledge, the primary focus of the daily check is to make sure the nails that hold the rail to the wood have not lifted and pound in any that have. I'm sure they keep a look out of other things as well, but I think that is the primary purpose as the rail receives the most abuse and lifted nails can do a lot of damage to the train and riders if left unchecked. It doesn't include inspection of the entire support structure like an annual maintenance check would.

I know in some places they will put a little line of paint over the connection so that they can easily tell if it has moved if the seal in the paint is broken in any way. I'm not sure this is done on all wooden coasters but I've definitely seen it in a few places.

To my knowledge, the paint isn't so much to check for bolt slippage but to check for bold pre-tension. The amount of tensile force in a bolt is specified in a design to make the stresses in the joint behave properly. A common way to ensure enough pre-load is on the bold is to finger tighten the bolt, paint or scratch a line across the bolt and nut, and then turn the nut a particular amount of turns based on the necessary pre-load and the bolt geometry. It can be a cheaper alternative than giving every worker a sensitive torque wrench that they accidentally break and have to replace every month...

Wooden coasters generally use massive nails I believe, and the sheer number of them is probably partially for redundacy, so one broken one won't make a huge difference. This, presumably, allows for checks to be slightly less thorough, only looking for major issues.

Generally, structural redundancy isn't for something like this. Structures are designed to withstand a particular load (the design load). This load is statistically calculated and then a safety factor is applied to help account for "unknowns" such as property variation or reasonably unforeseeable loads. This is really where structural redundancy lies. Structures are not then designed with additional redundancy such that part of the structure may fail and still bear the design loads. Generally you just barely handle design loads and that's it. If part of the structure fails and design loads can't be handled, that's a serious problem.

3ds Max Track Importer for No Limits 2
NoLimits Coaster

^that's looking very nice already!

Today I came across a new bug when I tried to import a coaster made with FVD. Basically the script crashed while parcing abbreviated numbers (3ds Max turned 0.000001 into 1e-06 and the unit conversion function didn't like this). I fixed the problem by letting the script set the system units to meters during the import process. This eliminates the need to convert the coordinates to system units and thus abbreviated numbers aren't a problem anymore. As a byproduct this also eliminates the need for 2 seperate files for dots or comma's as decimal seperators.

In short: There's now one script that should work for everyone and hopefully all the bugs have been solved :P. Go get it in the first post.
