Peppa and George have come to play at Granny and Grandpa Pig's house. Grandpa Pig has been very busy building a fantastic little train called Gertrude. He takes them on for a trip on the little train and it's not long before other children have climbed aboard too. All are agreed that Gertrude is the very best train in the whole world. / Peppa and George are going to see their big cousin Chloe. Today is a special day because Peppa and George have a new baby cousin: Chloe's baby brother Alexander. Alexander doesn't really do very much so Peppa, Chloe and their friends have fun pretending George is a baby.
