下面一段是来自2017年高考英语北京卷的听力材料：

It’s 8:00 am, and I’m on the platform at Sullivan Station. I’m waiting for the train to central station. I’m noticing that they’ve made improvements to this station. It’s cleaner, there are benches to sit on, and there are the arts on the walls. Because of that, this part of my trip has become more pleasant. Now it’s 8:30. I’ve arrived at the central station. The No.3 bus is in the weary side, and the bus is often very crowded at this time, so I choose to walk to my office. Still I have to say that trains and buses and walking are all better than driving. Traffic is getting worse every day and parking is more expensive. I guess it’s worth leaving my car at home. This is Jenny Waxlo reporting.

请问The No.3 bus is in the weary side是什么意思？特别这个weary作何理解？句子是不是有拼写错误？
