Fire officials in Pittsburg continue to investigate the cause of last nights blaze at the Kansas City southern rail station. It`s the second time this month fire caused damage to the now abandoned building. Last night`s fire gutted the inside of the old storage facility for the railroad. The fire marshal determined the fire was set by someone, they just don`t know if the blaze was intentional. When they first arrived on the scene water pressure to the building created a problem for fire fighters but pressure was restored and the fire extinguished from outside the building.
