I am writing to tell you about our experience on Train 2315 the other day. It is a train_____ goes from Winston to Stenberg.
This train was never late before， but last Thursday it did not get to the station____time and my friends and I had to wait for nearly fifty minutes. The train was supposed to____
_the station at 9：10 am but it was 10：30 am when it set off（出发） in the end. Officials at the station neither said sorry to us___
__gave us any reason for the delay(延误). On our way to Stenberg it stopped for ___
___ thirty minutes and still nobody told us why.
What’s more， the service on the train was also very poor. The trip more than five hours. However， we could buy__
___but some soft drinks on the train. Worst of all， something was wrong with the air conditioning(空调) and the temperature reached 38℃ before we arrived in Stenberg.
All the passengers on the train were so angry that they asked me to write this letter to your company. We hope you can give us some explanations and improve your work later.
We are looking forward to___from you.
Yours，
John Armstrong
