Gyah, I already have a possible plot ready for approval. =_= How about this... It's (kinda obviously) partially based off the song Sand Scraper....
[Male lead] is a young man in the early 1900's. He is bored of his life in his bland city of iron and metal and industry, but doesn't have enough money to move it, so he decides to stow away on a train called 'The Sand Scraper' that's recently arrived in town. However, not long after the train leaves the station, he is discovered by the conductor of the train, a girl about his age named [female lead]. Displeased that she has a stowaway on her train, she puts him to work on the train as, at first, one of those guys that shovel coal into the engine.
He meets his new 'co-workers' and finds out that they all come from different backgrounds, but ultimately, were all recruited as workers on the train in a fashion not unsimilar to the way he was recruited. So after a song or two, the train arrives at it's first stop.
That's when [male lead] finds out that the Sand Scraper isn't just any train. It is a train that has the ability to travel through time and space, and has the duty of picking up souls of the dead, and transporting them to the realm of the dead.
So basically there are several stops, where we see a couple of mini-stories and people live and die, finally picking up the soul and departing for the next stop.
At the end, the [male lead] sees that their next stop is his home town, and watches them pick up the soul of his sister, who died of grief and sickness after he left. Horrified, he says that he wants to get off, but [female lead] just laughs and says that once you get on the Sandscraper, you never get off again.
So... What do you guys think?
