The fire has already been put out and contained.
A bus has caught fire at Walt Disney World in the Transportation and Ticket Center (TTC) bus lot. The bus appears to be a third-party bus and not a bus operated by Disney.
By the time Mike of Blog Mickey reached the scene, the fire was put out. However, you can clearly see the damage on the bus – back right.
According to the Blog Mickey owner and writer, traffic is currently being diverted away from the TTC bus loop. However, traffic will be opening back shortly.
