This is an interesting story and has some great potential here. I've never been on that train ride and now I want to try it out sometime. I also never knew that Grove Farm has spent so much money in trying to preserve our culture. That is pretty cool.
However, this script has a few issues with it. Your 5 points need some work. Points 1 and 2 are very similar and it's possible that they could have been combined. If they were kept apart, what I need for point number 1 is to know all about the train ride itself. When does it take place? Where does it take place? How much does it cost? All of that information has to come out in your sound bites that you use to support it. From the first sound bite you used, it talks more about the museum. The second sound bite talks more about the actual train and other train items. None of this talks about the train RIDES. I need to know about the train rides first and then you can move into talking about the museum second. The VO for point 3 could also use some work. Saying that they are building the tracks to "give even more knowledge about the plantation" isn't very strong. With some work, you could definitely write a better VO. Then that second sound bite for that point talks about the museum which could go up higher in your script. Your fourth point is about the problem in building the extension, the cost. However your first sound bite for that point doesn't really help with that point and your second sound bite just says that the expense is the problem. How much will the extension cost? There is nothing mentioned about how much this new extension will cost so that point is weak. Then your last point doesn't do much better. It seems like you just wanted to finish up the story. Maybe you didn't have enough info to present a stronger closing? Did you not interview any passengers on the train? I don't see anyone but Grove Farm people in your story.
With some extra work, you can rearrange some of your sound bites around to support your points better but it also sounds like you may not have enough information here. Overall it's not bad. It does need some work though and for that I'm giving this a 3.3 or a B-.
Write something about yourself. No need to be fancy, just an overview.
