When can I build monorails?

[Fraoch]

Hello:

I'm playing Simutrans 110.0, pak64, on Ubuntu Linux 11.04 64-bit.

When can I build monorails?  The simulation is now in 1942 and my monorail tools show that I can remove monorails, build various signals, build a monorail depot and a storage column, but I cannot build any monirails.

Is there a year when monorails become available?

Thank you.

Monorail comes available in 1964.

You can check that by the way by starting a new game without timeline and look at the introduction dates of the monorail vehicles.

Great, thank you!

BTW a strategy question - is there an advantage to monorails over trams/light rails?  Without being able to build anything yet, I do see one advantage - grade separation.

The main advantage is speed: you can reach 160 km/h on monorail. You can't do that with trams...
The main disadvantage is space: you can lay tramtrack on roads, you can't do that with monorail.
