Ian Brooks:
Couple of questions
The line from Oslo to airport
1 is it a dedicated line or does it run into a very major rail junction/terminal
2 does it have any pick up/drop off stops en route
1. It's sort of a dedicated line (design speed 270 kph) between OSL and Oslo S (Oslo Central Station). The reason for me saying sort of is the line is shared with Inter City trains. At the half way point Lillestrøm is a junction with 10 parallel tracks, and obviously the Oslo Central Station is a serious junction with 18 parallel tracks. The Airport Express Train continues after the central station on the ordinary tracks below ground westward and coming in day light at Skøyen. In one year the local traffic will be separated from Inter City and Airport Express as the new high speed tunnel between Lysaker and Sandvika will open. Between Sandvika and Asker there is already a separate high speed tunnel separate from local traffic.
2. Departures 16, 36 and 56 minutes past the hour from OSL will stop at Lillestrøm before Oslo S and continue all the way to Drammen stopping at the stations shown above. Departures 06, 26 and 46 minutes past the hour from OSL will not go direct to Oslo S which is also the final stop.
