Hey please help me someone - whats the fastest way to get to the west railway station from the Beijing airport T3.

This is too late for you, but I hope it helps other people. There are two ways:
1. Take shuttle bus line 7 to the train station directly;
2. Take airport Express Train to Dongzhimen, then transfer to a taxi to your destination.
As it will be during the morning rush hours, the duration shall be a little longer than an hour.
