Rev. W. Awdry 
Thomas Gets a Snowplow (Thomas & Friends) 

Winter is coming and Thomas, being a small engine, needs to put on his snowplow. Thomas hates his snowplow; he thinks it makes him look funny, and when he has it on, the other, bigger engines tease him. But Thomas saves the day when a big storm comes up and Toby is stuck on his branch line.From the Trade Paperback edition.
