bahn de schedule

Just went through this with another poster. There is track work going on for a section of the Munich-Salzburg line from June 7 to June 12. There is a replacement bus between Teisendorf and Freilassing. So the train runs (check the schedule), but you all get off the train at Teisendorf and load the waiting buses that then take you to Freilasing station and you continue on to Salzburg on the train. Think of it as a repairs going on an Interstate and they close one lane of traffic each way to fix the highway, thus slowing everybody down. It's normal in the summer (construction season)..

thank you...coming back is even more convoluted because they state high passenger numbers

Just take the Flixbus.

They are only showing high passenger numbers on the route that goes from Salzburg to Muehldorf, then transfers to a train to Munich. Stick to the Merdian route with the replacement bus, even though at least one of these show taking 2 replacement buses. Weekends is when they do a lot of repair projects on the tracks.

As far as Flixbus goes, I guess if you bought a Bayern Ticket, you don't want to pay for an extra bus ticket.

If you query for June 8, then all connections shown do run on June 8. Ignore the note - it is poorly worded and supposed to say: "This precise connection is not available every day. It IS available on June 7th, 8th, and 10th-12th." In this case, the given days are the ones when track construction takes place - normally, there would be simpler connections.

The DB has no way of predicting the load on these trains because they cannot be reserved. This is just a global warning, whose background is that the trains on this route must be shorter than on the direct route because of the platform lengths at the stations on the way and because at some times of the day the trains between Munich and Mühldorf are already overcrowded with commuters. The problem has been around for decades, but the DB don't want to do anything about it and are waiting for the federal government to pay (which they apparently are about to do now).

On the other hand, for SEV transfers there is usually a sufficient number of buses available. The DB contracts local bus companies and, depending on the number of passengers boarding in Munich or Salzburg, resp., orders the corresponding number of buses to the transfer station. So that's the way to go.

Just take the Flixbus.

There are not many Flixbus connections between Munich and Salzburg and on the days in question they are unusally expensive on the Munich - Salzburg leg (€26 one way pp for the departures at 7:30 and 9:00).

Taking an SEV bus is no big thing in Germany. I've done it many times. The buses load (usually) in front of the station right after the train arrives. The detour only adds a few minutes to the trip.

Here is a map of the Freilassing Bahnhof showing where the SEV buses will be waiting.
And here is the map of the Teisendorf Bahnhof showing where the SEV bus will drop you off.

BTW:
SEV = Schienenersatzverkehr = Rail replacement transport
In case you wondered.

thanks to all that responded. I just returned from my week in Bavaria. Considerable work being done between Munich and Salzburg. I found that the diversions...Rerouting and bus travel very manageable. However, I discovered that my credit card did not work in the ticket dispensing machines in the hbf and the other rail options of munich. The ticket machines require a 4 digit pin. Credit cards normally have not pins. If they do, it reflects as a cash advance. Checking with my credit card company for my Sept excursion to Europe.

The PIN thing comes up rather often here. A PIN used in a ticket-vending machine will not make the transaction a cash advance. Also, reportedly, sometimes just pressing the "Enter" key or will work--but not always.

The credit card absolutely has a PIN. Buying a train ticket from a DB machine using your US credit card, you will be asked to put in your PIN in order to complete the transaction. I thought this was strange the first time I saw it, still punched in the PIN, a second or two later the transaction goes though. No PIN, no DB ticket from the machine
