Tracking counter in nested for loop

I'm currently working on a small assignment for school.

I need to print the current station where the train is at the moment and the stations that are left from the list.

I have used a nested for loop, but I can't get the inner for loop to work properly. Do I need to create a variable with +=1?

My code: 

train_station=['Amsterdam-Central','Amsterdam-Amstel','Utrecht']

for x in train_station:
    print("Current station is: "+x)
    print("Stations to go: ")

    begin=0


    for y in range(begin,3,1):
        print(train_stations[y])

My output:

Current station is: Amsterdam-Central
Stations to go: 
Amsterdam-Central
Amsterdam-Amstel
Utrecht

Current station is: Amsterdam-Amstel
Stations to go:
Amsterdam-Central
Amsterdam-Amstel
Utrecht

Current station is: Utrecht
Stations to go:
Amsterdam-Central
Amsterdam-Amstel
Utrecht

You're almost done, you just need to increment begin on each iteration.

train_station=['Amsterdam-Central','Amsterdam-Amstel','Utrecht']
begin = 0

for x in train_station:
    print("Current station is: "+x)
    print("Stations to go: ")

    begin += 1

    for y in range(begin, 3, 1):
        print(train_station[y])

And a more pythonic solution:

for i, x in enumerate(train_station, 1):
    print("Current station is: "+x)
    print("Stations to go: ")

    for y in train_station[i:]:
        print(y)
