Any experience with eminent domain?

[Jesse Castro]

I purchased 5 acres and a run down small house just north of Houston, TX. I now find they are interested in building a railroad though the back side of the property and the company says they would want the entire parcel. I personally don't want to sell but I understand they could ultimately use eminent domain if I refuse. The house needs a total rehab,  and the recent update makes me want to put the brakes on this project. For those with similar experience would you continue improving the property? or just stop and wait to see what the outcome is? it seems to me that the improved property will fetch a higher market value if eminent domain is ultimately used.
