Hej! Hoppas alla mår bra.

I have been checking on google maps for ways to go from Göteborg station to Trollhättan but it only gives a route that goes through Udevalla which is strange to me.

I need to be there in time since I have a job interview and dont want to give a bad impression so I would appriciate some help.

I have the interview at 08.00 and was thinking to leave around 06.00 in the morning especially since I have to take the local tram as well from Trollhättan central to Ladugårdsvägen 12. So what train should I take from Göteborg C toward Trollhättan and is it better to buy a ticket on Vasttrafik or SJ app ?!

Thank you in advance.

Update: Thank you guys for all the help and suggestions. I made it safe and in time for my interview. Very thankful to each one of you
