Placement 
of the vending machine 

1. the first placement of the vending machine was between the sliding door of the train and the sittings where it puts near to the passengers so they can get immediate solutions, it may helps smelly people to prevent bad body odor or non smelly people to avoid bad smell

here we try to make it smaller and also shorter so it can fit perfectly and save place. 

2. some researches of the another placement for the vending machine. where we try to put it on the waiting platform so people can prepare themselves before and after their go inside the train and purchase the items easier during the peak hours.
