Rumble Rescue is a magazine story. It was republished with some small alterations in 2012 under the title, Messy Rescue!
One damp morning, Rosie and Edward are waiting at a signal in the countryside when they hear a rumbling sound. As the engines set off, Edward whistles urgently. A landslide has blocked Rosie's line. Rosie is very grateful; Edward has saved her from a nasty accident. Later, Rosie and Edward return to the main station. Rosie is low on coal and she rolls towards the hopper. Then there is another loud rumbling. Edward orders Rosie to stop as a load of coal is released from the chute and onto the rails right in front of Rosie! Edward has saved Rosie again!
Then it's Rosie's turn to hear a rumbling sound and quickly calls out to Edward. But Edward doesn't move as there's no danger. Edward explains that the rumbling was only his old boiler playing up.
