Good morning. Is it me? Sometimes when boarding a Locomotive I am unable to get in the seat, as there is a driver there already. On other occasions both seats are occupied.
Press the number 'one' on your keyboard. It should put you right in the driver's seat. It doesn't matter if there are other 'drivers' in the cab; one of them will be YOU!
Are you talking about Train Simulator or Train Sim World? If Train Simulator then just press 1 and you will be in the driver's seat view automatically If Train Sim World then walk up to the seat and press E and the person in the seat will disappear and you will sit down If TSW please note that this is the TSx forum and there is a separate one for TSW
