The Fat Controller was true to his word, two weeks later, a brake tender was dropped off at Edward's station by Henry. Edward looked at it curiously, whilst the brake tender scanned the yards. His grey eyes then saw the blue engine next to the water tower in the yards and grinned.

"Hello there!" he called, "my names Weighty and you are...?"

"My name is Edward," smiled the blue engine, "I'm guessing you're here to help one of ours?"

"Yes, I am," replied Weighty, "I am to assist this BoCo lad with braking power, wouldn't be here if that wasn't my purpose!"

"Good," said Edward, "BoCo is arriving soon, I hope you two will get along!"

Edward shunted Weighty into a siding and went to fetch his coaches. Just as he pulled them into the platform, BoCo rattled into view with a goods train and coming to slow stop next to Edward's train on the second line. His new buffers looking splendid.

"Your new brake tender has arrived," Edward stated, "I've shunted him into a siding close to the sheds so you can talk with him."

"Oh, um... thank you Edward," said BoCo, a little hesitant.

The old blue engine sighed. "You know the Fat Controller couldn't do much about the situation BoCo," he said, "after that incident it has been confirmed that any steam engine going at that speed and distance would've stopped or hit the back of the train less harder than you did."

"I know that, but it's humiliating!" cried BoCo.

Edward sighed. "I would advise you to just talk with the brake tender," he said, "who knows! You might get along with him."

The guard then blew his whistle, and Edward set off up the branch line leaving BoCo with his trucks. BoCo soon shunted the trucks into their proper sidings in the yard and went over to the brake tender.

"Hello!" called the brake tender, "you must be BoCo, my name is Weighty."

"Nice to meet you," replied BoCo hesitantly, "how are you getting on?"

"Oh! It's lovely lad," exclaimed Weighty enthusiastically, "never been on such a lovely railway! Been here long?"

"Only for seven years."

"Jeez! I'm surprised that I haven't been called in earlier to help you," stated Weighty, "being here that long and not needing a brake tender!"

Of course, Weighty never meant to offend BoCo, but the big diesel growled viciously at the brake tender. "I managed just as well without one of you," he said, "the only reason why you're here is because of some silly reason of me stopping in time."

Weighty chuckled lightly, he was beginning to find BoCo quite intimidating. "Say, can I join you on your next journey?" he asked, "it could make us talk more whilst at it!"

BoCo was hesitant, but his driver thought a grand idea. So, with his driver taking over control, the big diesel buffered up to the eager brake tender and they set off with a small train of trucks down the mainline. Whilst BoCo coasted along the line, Weighty wanted to chat to him, but unfortunately for him it was mostly one-sided since BoCo only said simple replies. They finally arrived at the big station and dropped off the trucks behind the station and in the yard.

Whilst refilling up with diesel, James the Red Engine came into the yards. He had not fully forgiven BoCo for smashing into the back of his train and was slightly satisfied when looking over to see BoCo with the the brake tender dozing in the sun, whilst he tried to make himself as invisible as possible.

"Hello BoCo," he called with a wry grin covering most of his face, "is that your brake tender?"

Before the big diesel could reply, Weighty spoke out. "Indeed, I am lad, my name is Weighty! What's yours?"

"James."

"Nice name lad," chuckled Weighty.

"I see you've made BoCo quite silent," continued James slyly.

"Is he always like this then?" asked Weighty.

"Well of course not!" replied James, "he's never been this quiet when he's our yards."

"Must be me then!" Weighty joked.

"Yes..." said James, "must be."

"Come on James," called his driver, "we better head to the sheds!"

James agreed, and steam came out of his pistons. "Nice talking to you," he said, "and make sure you keep BoCo in line for me!"

"Don't worry lad, I will!" BoCo rolled his eyes whilst James puffed away, muttering 'lad' under his breath with a grin that crinkled his cheeks.

Soon enough BoCo was due to take a slow goods train to the mainland. He was ordered to take Weighty along too. BoCo was still embarrassed by having a brake tender but said nothing as he collected the first part of the goods. Slow goods trains are mainly kept for the mix-traffic engines such as James or Bear but were unavailable so BoCo was ordered to take them instead. Luckily, none of the engines on Thomas' branch line were seen, and no engine had chance to stop at Crosby whilst BoCo collect some more trucks. The big diesel was incredibly grateful for this, as he rumbled along the line whilst Weighty hummed ahead, he had noticed on how it was much easier to stop with the brake tender. He decided not to mention it though as he carried on down the line.

But things would take a turn as they reached Edward's station. As BoCo left his trucks on the mainline so to collect some more trucks, there was trouble, the points were set against him when he was trying to move over and Weighty's front bogie came off the rails.

BoCo growled crossly, as his driver clambered down to inspect Weighty. He thought Weighty had done it on purpose. "I knew brake tenders were rubbish!" he cried out loud, "they do this to make diesel engines look like fools!"

"I'm sorry lad," Weighty replied, "but you see-"

"Don't bring any excuses into this," cut in BoCo, "you did that on purpose!"

Luckily, Weighty had not blocked the path of BoCo reaching the trucks, so the workmen, signalman and driver decided to leave Weighty there until Edward got back and BoCo would carry on without the brake tender. BoCo was still cross and left the station in a furious temper leaving an extremely uncomfortable, but guilty Weighty behind.

Whilst BoCo was continuing with pulling the slow goods, he realised in comparison to having Weighty or not, the brake tender was actually quite helpful. The train arrived a few minutes late though at Barrow and BoCo and a mainland diesel had a small quarrel before their drivers forced them away from each other.

BoCo was nearly done for the day. He had one more trip down the mainline with a fast freight train back to Tidmouth. He felt this trip would be a lot better without Weighty though and half an hour later was pulling the train back to Sodor.

As he was travelling along the mainline, he was thinking about what he would say to Weighty when they next met. But he was too busy thinking that he was being rough with the trucks, the trucks were insulted and wanted to pay BoCo out. They decided to play out their plan when they reached Gordon's hill. The big diesel stormed up the hill with the trucks coming quietly behind him. Then there was trouble, as BoCo began to break so he could have the trucks pin down their brakes, the wagons decided to play out their plan.

"ON! ON! ON! ON!" they screamed and banging their buffers, they pushed a shocked BoCo down the hill.

"HELP!" cried BoCo, his driver applied the brakes, but it was useless against the laughing trucks, he rattled down the hill and under the stone bridge. He went around the bend at a tremendous speed, almost coming off the rails. He tried to brake harder, but he couldn't, as sparks came between his wheels and the rails, he and his train carried on towards Edward's station.

Meanwhile, Edward had pulled Weighty back onto the rails and was about to shunt the still gloomy brake tender into a siding when they heard BoCo's horn, Edward gasped when recognising the three toots with the last one being the longest. "That's the emergency code," he said, "he must be endanger."

"Must be a runaway on that hill," said Weighty, "Edward, push me onto the mainline."

Edward looked at Weighty in shock. "But you'll get smashed to pieces!" he exclaimed.

"Not if I keep on rolling," replied Weighty, "just uncouple me and push me as hard as you can onto the mainline. Do it quickly lad he'll be here any minute!"

A shunter quickly uncoupled Weighty from Edward. The BoCo came around the corner, he wasn't going as fast as he was going down the hill but was still going over the speed limit. Edward quickly blew his whistle to warn the signalman and gave Weighty a mighty shove. The brake tender rolled over the points and onto the mainline, quickly the signalman changed the points just in time as BoCo screeched over them with laughing and screaming trucks.

He gave Weighty a mighty bash. Both diesel and brake tender seethed from the sudden hit. But there wasn't any time to lick the wounds as Weighty felt his wheels going much faster than before.

"Right," he said firmly, "don't worry BoCo lad, I've you!"

Weighty began to hold his weight onto the rails and immediately, BoCo felt the sudden change of braking force with the train. They began to slow down. The trucks growled crossly and tried to push them further on.

"GO ON! GO ON!" they rattled.

"Oh no you don't," said Weighty, as held back even more, BoCo also did too and with each other's help, the trucks eventually tired out and the train came to screeching stop at last. The trucks all grumbled with disappointment whilst BoCo and Weighty gave a sigh of relief.

Edward soon came to see if everything was alright. "Are you alright BoCo?" he asked, as he came up next to the big diesel.

"Yes I'm fine, thank you Edward," replied BoCo, "if it wasn't for Weighty though well... I would be in a sorry state!"

"I should think that too," came a voice, BoCo jumped. Out of Edward's cab, was the Fat Controller.

"I heard about the derailment at Wellsworth BoCo and your little temper lost there," he said, "reports say that the points weren't set right and Weighty derailed on them whilst they were against him. Even though I'm glad you got the train to Barrow without any further mishap, I would want you to keep your... weight on the rails with you at all times whilst on the mainline, accidents and incidents like these can happen and I don't want to receive any reports or bills on my desk because of a crash."

BoCo blushed. "Yes sir, I'm truly sorry sir."

The Fat Controller nodded. "Make sure you keep Weighty with you whilst on the mainline," he said, "you can continue on the journey with him now."

"But sir," said BoCo, "I might be damaged from this incident."

"Trust me BoCo," said the Fat Controller, "you seem fine to me."

He walked back to Edward's cab and the blue engine reversed back up to his station whilst BoCo carried on with a coupled up Weighty in front. Both didn't say anything at first, but once going through Thomas' junction, BoCo finally spoke up.

"I'm sorry I treated you the way I did," he said, "I just didn't want to look like a failed engine to the Fat Controller and brake tenders such as yourself were usually seen as support for diesels and well, some classes of diesels thought diesels who have them showed weakness."

"Nah, it's completely fine lad," smiled Weighty, "I understand because I've seen those diesel poke fun of the other diesels who push us around. We do are best though, some diesels who need us despise us, whilst others enjoy are company."

BoCo smiled. "Let's restart from the beginning," he said, "I'm BoCo."

"Please to re-meet you BoCo, I'm Weighty."

After that, BoCo and Weighty became good friends. BoCo never leaves Weighty behind when he works on the mainline and always enjoys his company. But when BoCo doesn't need the brake tender, you can see Weighty dozing in the sun whilst sitting in a siding near the sheds at Edward's station, completely content with himself and happy to be a part of the North Western Railway.
