Concise travel directions for public transportation

Question

I'm writing down travel instructions using public transportation. It's a list where each line should essentially contain three pieces of information: what line to use, what direction of the line (i.e. the name of the final destination of the line) and the name of the stop where to exit the vehicle. I've got some concerns about the latter two station names getting mixed up. I'd like my formulations to be short, yet clear, and ideally something a native speaker might be using as well.

Some alternatives that come to my mind:

1. Bus 123, direction Foo, exit at Bar
2. Take bus 123 to Foo till Bar.
3. Take bus 123 towards Foo to Bar.
4. Take bus 123 direction Foo to Bar.
5. Take bus 123 heading for Foo, leave at Bar.
6. Take bus 123 to Bar, direction Foo.

In particular, I'm unsure whether the word “to” would indicate the end of the line or the stop where to exit, or perhaps both depending on context.

Answer 1

If you use to, more context is necessary since both "Foo" and "Bar" are in the "to" direction.

To break down your instructions

Which bus to take

Take bus 123

Which direction to go

going towards Foo
in the direction of Foo
heading for Foo
for Foo
to Foo

Which stop to get off the bus

get off at Bar
until Bar
until you get to Bar

It is also useful to say either how many stops or the expected travel time until the destination.

You could also phrase it as

Take the Foo bus, number 123, until you get to Bar
