This episode is one of the shortest episodes in the series. This is not a reflection on the vast amount of planning, set adaptation, filming, editing, animating and lastly stressing that went into it!

Tavish the J39 was chosen as the story's main character as it would introduce him properly, and hopefully give the audience a few much needed laughs after the drama of Episode Six.

The snow set was carefully worked on, using an identical baseboard to the normal set (which was being re-designed for the Sir Ralph Wedgwood Trilogy of episodes) and re-used a lot of the components found on the normal set, such as the shed, the goods platform, the station, the signal gantry and the windmill. The snow was a mixtures of Scenic Snow (from the Scenic products range), talcum powder and soap powder, that was stuck down carefully with glue in selected areas, and powdered over other areas, such as the buildings and plant life.

The most realistic shot of the set, the one that sums up the snow set's quality, was the shot of Tavish on the point work near the start of the episode. The problems came with keeping the tracks entirely clean for running, and this meant that from time to time, the film makers found they really did have to keep the tracks clear of snow!!! Life imitating art and all that!

Tavish's snowplough was made from plasti-card and painted appropriately. It was felt that a more traditional design of snowplough should be used, although a new one (which is more Eastern Region looking) was been made for the 2008 Christmas special, Silent Night.

As far as stories are concerned, this one was wholly more fun, with Sir Ralph and Tavish's back and forth argument being the highlight of the episode. It was also the first time that all the members of the main cast had lines in an entire episode together: the other episodes were of course, mostly two-parters and hence from part to part, not all of the engines spoke.

Episode Seven was a monster to make, and, compared to the earlier episodes, a great improvement, both visually and in script (which I felt was tighter, and for the most part, funnier). It was such a boon to make this episode, terrific fun playing around with the models and lighting. It would be well over twelve weeks until the next episode; and then began the web of intrigue surrounding a certain A4 Pacific...
