4th Gen How do I get into Goldenrod radio tower?

[eeveetree9]

I have defeated all the gym leaders up to Pryce, and received the call from Professor Elm, and Team Rocket have taken over Goldenrod, but I have no idea what to do now. I looked it up, and from what I can gather, there's supposed to be a Team Rocket grunt in the magnet train station, but I can't see anyone there except a guard telling me that the train isn't there and he should carry the passengers on his back. Please help meeeeeeeeeeeee!

Try going into the underground subway.
You should see a lone person that's dressed up as a Rocket Grunt. He actually helps you out by disguising you as a Rocket Grunt, so you can gain access to the Radio Tower floors.

it's really odd that you haven't seen the grunt considering he's supposed to be there.
