if you come to Big City Life you need patience. lol First to load in cache and then to drive with public transportation like bus and train. (but you can drive with taxi or any other car too)
There are already driving 2 blue busses with each 40 min routes. The green bus is only driving close to shops and is in the city. This tour is just 7 min long.
The Maglev Tram brings you also to suburbs and country side. There are two trams. But one tour is 20 min long.
The Santa Fe is the fastest and just needs 15 min for a circuit.
The Sydney City train is slow and needs 23 min for a circuit.
So if you wait at bus stops or at railway stations, then take your time.
It could be that the Santa Fe is not driving. But then it has home at landing point railway station and you can start it by yourself. Just click on locomotive and you get blue menu. First you click "align" and then "start". That's it. (Listen if the Locomotive really says "align" and "starting". Align is important. If it has not said align then click once more align.)
It all depends how long the grid is running without a restart and how many people are on the whole grid. Usually if the grid is running one day all is working fine. But after two days it gets slower and if many people were on the whole grid the more. On Decadence Grid is also the biggest mall in opensim "Grimm". Grimm has usually always traffic. Just the Athena clothes building is 1 km long and you get all there.
But usually one day after restarting grid, all works perfect how it should.
Anyway there is no guarantee that all busses and trains arrive punctually, although I am German. lol Our Deutsche Bundesbahn is not anymore that punctually too. lol

But you can also fly with helicopter or planes. The planes start at airport, of course and fly in altitude about 200 meters. One starts at Hangar and one at Terminal 6. There was another at terminal 4 but this would have been too much. lol Be sure you have a good computer and can use 1024 distance draw. Otherwise you would not have fun.
For the 4 helicopters it is the same. But the blue helicopter is just flying at 60 meters altitude and you can reduce distance draw to enjoy. The helicopters land at different points. Just the emergency heli starts and lands on roof of the Broadway building. Here you can watch a flight with it over central park.
