Toby's Megatrain is an upcoming Series 26 episode and From the Railway Series!
Toby does the shunting at Knapford Harbour while Percy takes Annie and Clarabel. There are many trucks, and Toby is worried he may run out of water at some stage. One morning Mavis is unwell and is late to deliver her trucks, and so Toby eventually racks up a load of forty-eight trucks. Toby, forgetting his small tank and the uphill journey, decides to pull all forty-eight trucks at once, and at Elsbridge he discovers the watertower is empty. Toby's driver says they will have to go fishing like Thomas, but he is only joking and Toby goes to Ffarquhar to take on water, then runs back to take the trucks.
