I run trains on the
track plans that I've created in RailModeller?
Answer: Yes, but only when using RailModeller
Classic (version 4.1). Instructions are provided here.
RailModeller-Pro is not yet compatible, since it does not
export SLIF files. If you would like
that feature added to RailModeller-Pro, please let them know.
Question: Why does
leave a Terminal
window open after I quit running it? Is that a bug?
Answer: Not a bug. To simplify development, iRunTrains
runs as an
OpenGL Unix application on Mac OS X. This means your Mac
starts Terminal when
iRunTrains, and it leaves the Terminal window open
after you quit. This is normal.
Question: I switched a
when a train was
driving over it, and the train came apart. How can I put it back
together? Is this a bug?
Answer: Not really a bug. Trains
can split apart because we have not yet implemented any checks
detect this condition. To put the train back together,
turnout the way you came in. The train should then rejoin
automatically. Or you can just reload that layout to start
Question: What is the
number of trains we can put together and the software can run ?
currently includes three default trains that cannot
changed. In a future release, you should be able to run up
simultaneously, with up to 100 cars per train.
Question: iRunTrains seems
slow or jerky on my Mac. Why?
Answer: Try quitting other application that may be running
resources. Also try turning off the iRunTrains help overlay by
"H". Is Time Machine doing a backup? That can slow things
down too. Also, consider restarting your Mac just in case OS X
having problems (though this is rare). iRunTrains requires a lot
computing power to run, so it may be that your Mac is just not
Question: iRunTrains really
my CPU and makes my
Mac's fan run
loudly. Is this normal?
Answer: Yes, this is normal. iRunTrains requires a lot of
computing power to
run, and this causes your Mac to generate more heat. This is
when you don't see trains moving, since iRunTrains is always
draw 30 screens/second. Apple designed
your Mac with a fan that automatically spins faster to keep your
cool under these
Question: How do I uncouple
couple individual cars?
Answer: Sorry, iRunTrains can't do that yet. This
is planned pretty soon though.
