keep standing ...?

[yamyam]

Hello, teachers.

Would you take a look at the following?

1. Both the train and the buses are crowded, so I have to stand all the way.
2. Both the train and the buses are crowded, so I have to keep standing in them.

Q1: Does #2 sound natural to you native speakers?
Q2: Does #2 express the same meaning as #1?

Thank you very much in advance for your help.

'The train and the buses are all crowded, so I have to stand all the way' is how I'd say it.

Only use both for two things:

'Both the train and the bus are crowded. . .'

Keep standing- this suggests a repeated action and one that you might be annoyed about. I would use this if complaining.

Thank you very much for the replies, Rover KE and Tdol.
Your suggestions are quite instructive to me.

Thanks again,
