BILLINGS, Mont. (AP) - Several factors are combining to make it more difficult for Montana farmers to get their 2013 wheat crop to Pacific ports.

The Billings Gazette reports (http://bit.ly/1j3NvzE ) BNSF Railway is seeing increased traffic due to oil and coal trains and the movement of record grain crops. The construction of more sidings to allow trains to pass each other also caused delays last fall as did extremely cold weather this winter.

Big Sandy farmer Lochiel Edwards says farmers are starting to get nervous that they won't get last year's crop to market before they start harvesting this year, which could potentially lead to lower prices.

CHS vice president of rail transportation Dan Mack says the rail construction should help in the long term, but in the short term there will be delays.
