The Purge: # 4692 Yardmaster: Caboose Expansion: Do you need this expansion?

About Yardmaster: Caboose Expansion, from BoardGameGeek:

The Caboose Expansion adds a strategic end game variant into Yardmaster that requires each player to attach the random Caboose Card they were assigned at the beginning of the game in order to win. The Caboose Expansion adds five new cards into the game. With The Caboose Expansion, Players shuffle the 5 cards and distribute them one per player. The Caboose cards are all value "2" and in order to win a player must not only meet the required point total but they must be able to "attach" the Caboose still following the value or cargo type restriction.
