Best Engine Ever is the eighteenth episode of the nineteenth season.
One day, Connor and Caitlin are having a race when Caitlin has to stop suddenly; Emily has broken down on her track. Emily apologises, but Caitlin says she shouldn't as everyone breaks down sometimes. Emily then asks Caitlin to push her onto a siding, but Caitlin is hesitant and changes tracks to get around her instead.
It isn't long before Caitlin comes back after dropping off her passengers. Caitlin backs up to Emily and is coupled up. Caitlin then proceeds to pull Emily to the Steamworks. On their way, Connor puffs up and Caitlin decides to race him. Connor is winning until he has to stop at Kellsthorpe Road. Emily is extremely impressed with Caitlin.
Caitlin drops Emily at the Steamworks and leaves her. Emily is still in awe of Caitlin and thinks she must be the best engine ever. Victor reminds Emily that speed isn't everything, but Emily says she loves Caitlin's sleek shape, too. Emily imagines herself as a streamlined engine and asks Victor if the engineers can change her shape, but Victor tells her she's great just the way she is.
A few days later, Emily has been repaired and is back at work on the main line. Caitlin comes up alongside and remarks how well Emily looks. Emily tells her that she will never be as good as Caitlin, but Caitlin says that's nonsense and tells her that she's a brilliant engine who gets to pull a wide variety of trains while Caitlin only ever pulls coaches.
Emily sadly pulls into the shunting yard with her train of trucks. She tells Thomas that Caitlin is better than her at everything, but Thomas is sure that isn't true. Then, Marion arrives and says that Emily should be proud to be herself, but Emily takes no notice and puffs sadly away. That night, all the other engines try to cheer Emily up, but nothing works.
One day, Emily has to make a delivery to Ulfstead Castle. When she gets there, she is surprised to see Caitlin being examined. Caitlin explains that her driver had heard a strange noise and is just checking her over.
Emily heads back down the steep slope, away from the castle. Then, she hears Caitlin calling for help; her brakes have failed and she's rolling along, out of control. She runs into the back of Emily who knows she has to slow Caitlin down or there will be a bad accident. Emily applies her brakes and bravely manages to stop Caitlin at the bottom of the hill.
This time, it's Caitlin who has to go to the Steamworks and Emily is delighted to be the engine to take her there. Caitlin's skirt has been damaged and she reveals that is why she never shunts. Now, Emily understands why Caitlin didn't push her onto the siding. Caitlin says she wishes she had buffers at the front like Emily. Caitlin then thanks Emily for her bravery and says she is lucky to have a friend like Emily and Emily knows she is lucky to have a friend like Caitlin, too.
