I am currently going through a chinese textbook chapter about transportation. There are however some constructs I am not sure I understood very well. I would be very grateful, if someone could help me.

1.  I have the sentence: “火车快到了吧？”

Is this actually rather statement asking for confirmation than a real question?

So, one would translate: “The train arrives soon?” or “The train does arrive soon?”

A real question would be: “火车快到了吗”？ “Does the train arrive soon?”

Also: The “了” here indicates: The train is currently underway, has not yet arrived.

2. For trains one uses 次，for example T23 次

Are there similar words for other means for transports? Ships, busses, planes, subway

3.  How would one translate:

“The bus 287 from A to B arrives at T?”

A, B are are locations, T refers to a time.

My suggestion: “从A 到B 的287 路公共汽车到T.”

4.  What – 这儿有 mean?

Can one translate it with “there is” ?

For example:

Does “There is bus line 287” translate  “这儿有287路公共汽车” ?
