After a long discussion with the other TTTE Wikia staff members we have come to the conclusion that there is no further proof that the blue and white truck seen in the Railway Series needs to have a page. It was simply a random truck and Wooden Railway decided to make it and give it the name Rickety, as did Bachmann before they cancelled their truck which was based off of the Wooden Railway version. Therefore, "Rickety" was just a marketing name made-up by Learning Curve or whoever was in charge of the toys back then, similar to Derek not being named in the show except the merchandise called him Derek so he became known as Derek. The U.L.P. Van shares the same dilemma. There is no need for a page of a random truck.
Yes, I did see the message - we're not entierly sure if that order is correct even if it is on the DVD. For example, the episode list on the Season 17 page is in a different order than The Complete Series 17 page so it's best just to keep it the way it is for now.
