It sounds like you are sending a cargo train to Bobby, but you are low on the material he wants.

For example, if you're working on contract #13, maybe your train will haul a total of 10,000 U-235. If you have only 4,500 U-235 in inventory, then more than half your train will arrive at Bobby's station empty.

To check your materials inventory, click the "Materials" button in the top right corner of the game screen from any of your stations (Main, Second, Third, Fourth, Fifth).
