Boko's twin. Bill and Ben the twin engines worked between the China clay quarry and random docks at the end of Edward's branch line. Like most harbors Brenda is a very busy place so Bill and Ben always have lots to do but they're never too busy to have fun with the other engines especially Boko the diesel. One morning the shed form and was looking at Bill and Ben as they were prepared for work. Hmm name plate could do with a good polish he said to the drivers I'll take them off and give them a rub down while it's quiet. This gave Bill an idea. He let's play a trick on Boko he whispered to Ben. When Boko arrived at the harbor they were trunks all over the place very easy for small engines to hide amongst. Bill Ben where are you called Boko? You who over here a voice replied who's that it's me Ben I brought you trucks. Well stay there I'm coming over. Boko had just started across the yard when he heard another whistle from the other side. No I'm over here. So the cheeky voice again Boko headed towards who he thought was Ben but before he arrived he beat not there Boko I'm over here. Not again grown Boko he tried to work out who was who but with no name plates it was impossible. The twins thought it a great joke and wouldn't stop calling and whistling team at last Boko lost patience. Look whoever has got made trucks would you please bring them more to me I don't have time for this. In the end the twins gave in and gave Boko his trucks. Spoilers sport they cheeked it was only a bit of fun. When Boko arrived at Wellsworth he met Edward and told him about the twins. They wouldn't find it funny if someone pleaded tricks on them all the time he grumbled. How true said Edward and then he smiled actually I've got an idea listen to this. Later that day Bill and Ben were at the docks again when Edward arrived. You two had better behave yourselves we've got a visit you shortly. Oh said the twins who is it it's another diesel just like Boko he's from the mainland but he works on a heritage line a heritage line asked Ben yes said Edward like step me on the blue well railway he's heard all about you two and he's coming to give Boko a hand but he's very strict so mind your pees and cues mind are what asked Bill he means no more tricks laugh their drivers come along back to work Bill and Ben scuttled off while Edward smiled to himself all afternoon the twins kept a look at the Boko's twin they waited all evening and when night came their visitor still hadn't arrived you know how they could with with pulling our wheels said Ben as they went back to their shed yeah agreed Bill I reckon Boko's twin doesn't exist at all oh yes I do boom the loud voice Bill and Ben jumped then the shadow of a large diesel pulled up alongside the shed who's that they quivered I am cobo Boko's twin and you must be Bill and Ben I've heard a lot about you too and I know exactly how to deal with naughty engines like you unless you do as you're told and get my truck ready I take a clock sharp tomorrow morning is that clear then without waiting for an answer the diesel rumbled away Bill and Ben were unusually quiet that night the next morning at exactly eight o'clock Bill and Ben arrived at random with their trucks creeping into the yard they found a diesel waiting for them but who was it excuse me said then there was like are you Boko or cobo don't worry it's all in me chuckled Boko did you see me twin last night in sort of said Bill head would was right he was very strict and loud at it Ben hmm I see and by any chance did he sound like this boom Boko and then he began to laugh loud and long suddenly the twins understood it was you so your twin doesn't exist after all yes it was me said Boko when he'd recovered I couldn't resist although driver says there is no the diesel like me and he does work on a herited line over on the mainland but I don't know what he's like still if he does pay a visit one day we'll find out then what way Bill and Ben rather hope that they wouldn't
