2 adults need to travel on Friday, 6/26 from Salzburg HBF to Munchen Rosenheimer Platz. I am looking at the DB website and there are 3 options with widely different prices. Obviously, I want the cheapest one but not sure why the second option is so cheap compared to the other 2 options. Which one should we select?
11:00-13:00 2h RJX 262 for 115.40 euro
11:05-13:10 2h 5 min RES for 44 euro
12:00-13:40 ICE 118 1h 40 min for 94 euro
