OKLAHOMA CITY (AP) - Authorities say a tornado overturned several railcars and strong, straight-line winds damaged several homes and a business in southern and eastern Oklahoma.

No injuries were reported Tuesday, the second day of severe weather in the state.

The McCurtain County Sheriff's office says a tornado damaged a train east of Valliant in far southeast Oklahoma. No other damage was reported.

Elsewhere, Madill Fire Chief Keith Pruitt says officials aren't sure if a tornado or straight winds took off part of a home's roof in Marshall County.

In Carter County, emergency management director Paul Tucker says a severe storm sent a large tree limb through the roof of one home and knocked a mobile home off its foundation.

Sequoyah County officials say a store in Muldrow and several barns were damaged.
