TTTE - Bertie

Bertie is friendly and ready to help anyone in need. However, he can be quite cheeky and even boastful about himself, especially to Thomas, always joking around and teasing him about their races. He can sometimes be quite grumpy, always grumbling whenever he breaks down or gets stuck. He is always, however, easy-going and cheerful to everyone he sees. Unlike Bulgy, Bertie respects the railway and its engines, and serves as one of the many minds keeping the double-decker bus in line.

After Thomas became stuck in a snowdrift, Bertie came to rescue Thomas' passengers. He later raced Thomas after claiming he was the faster of the two but lost after having to stop at a traffic light.

When Thomas' fireman did not come into work, Bertie promised to help his passengers catch Edward's train. However, he was late at the junction and missed him at the station. Bertie chased after Edward and almost caught him at the next station, but arrived just as he left. Due to being able to climb hills better than him, Bertie finally caught up to Edward at the third station. Edward apologised to Bertie for the chase and the passengers cheered at him.

When the Viaduct was being repaired, the Main Line engines were delayed in bringing Thomas his passengers, thus making Thomas late in meeting Bertie at the stations along the branch. Bertie teased Thomas about being slow because of this and even challenged him to another race, but had to eat his words after breaking down. Thomas took his passengers home and called for help at the next station. When he was repaired, Bertie apologised to Thomas for teasing him and thanked him for helping his passengers.

Bertie was once chosen to take visitors to the Vicar's garden party and teased Trevor by calling him a "stick-in-the-mud" and old fashioned. However, he proceeded to get himself stuck in the mud and had to be pulled out by Terence. After that, Bertie thanked Trevor and gave him an apology for teasing him.

When Edward had an accident on the day before he was to take the Brass Band to a concert, Bertie had to take them instead but got stuck in the mud again. Luckily, Edward was repaired and took the Brass Band to their concert.

Bertie is continuously alluding to his race with Thomas and how he could win next time. He actually raced Thomas again and won after Thomas got side-tracked with collecting the sports medals.

Bertie and Thomas have seemed to continue this tradition of racing. However, in the seventeenth series, he was re-routed, giving him an advantage, though Thomas is still able to beat him occasionally.

In the nineteenth series, he, Thomas and Spencer got into an argument after Mr. Percival claimed two wheels was best; Bertie argued four wheels was in fact best. He tried to prove his point by taking the Duke and Duchess of Boxford to Callan Castle after both Thomas and Spencer failed to do so, but he too failed after receiving a flat tyre. Harold eventually came to the Duke and Duchess' rescue. Bertie later teased Thomas by telling him about what was on the other side of a mountain on his branch line. Thomas was cross by Bertie's teasing and became determined to find out what was there. Thomas eventually discovered it was a roadside billboard Bertie was describing, though he got into an accident while trying to find out. Bertie visited him at the Steamworks and apologised, though Thomas was able to trick him into believing that he was getting fitted with wings.

In Sodor's Legend of the Lost Treasure, while he and Thomas were racing, Thomas nearly collided with Toby while Bertie nearly collided with Oliver the Excavator. At Ffarquhar, he complained that he was always getting stuck behind slow construction vehicles since the construction of a new branch line had started. He was then seen on the road by the Harwick Branch Line. Sheep were in his way, but Bertie just smiled.

In the twenty-first series, Bertie ended up breaking down while he and Thomas were racing. This ended up with Thomas taking on his passengers but ended up getting requests for lots of unscheduled stops, which made him run late. However, Bertie was soon temporarily replaced by Bulgy, leading to Thomas running on time.

After being repaired, he shared the mantle of keeping Bulgy in line. Bulgy, however, was still up to his old ways, so Bertie had to remind him that The Fat Controller brought him back to help him with the passenger service; he later broke down due to struggling with passenger transport (flourished due to train halting courtesy of Bulgy). Bulgy took his passengers while Butch towed him away.

Later, when Percy created rumours of a railway show for little engines at Ulfstead Castle, Bertie took Thomas' passengers from Ffarquhar to Knapford after Thomas abandoned his duties to attend. you can be anyone else, unfamiliar or familar !!
