Eastern Railroad Discussion > CSX Palmetto FL. Sub. Question

Last Friday April 20 my wife and I drove north on US 41 to Ruskin to do some shopping.While passing Port Manatee I could see that the siding was empty of rail cars at about 10:00 AM. Upon returning around 11:45 am on US 41 we saw a whole string - 20-25cars that looked like grain hoppers. My question is what train could that be and were the cars loads or empties? So it appears that this train arrived at Port Manatee sometime after 10:00 am and 11:30 am so any info would be appreciated.

Thanks
