Later on, Sierra, Jacob, and Rosie were taking a train of stone from Anopha Quarry to Brendam. However, Jacob was very impatient, and did not wait for a brake van before leaving the quarry. Because of this, they had trouble getting up Gordon's Hill until Oliver, Cassie, and Kira came along and helped them up the hill. However, Jacob did not want to stop to uncouple Oliver, and this lead to Rosie and Oliver having an accident in Henry's Forest[2]. Sierra and Jacob later convinced Sir Topham Hatt to restore Glynn[3] and threw surprise birthday parties for Cassie[4] and Caroline[5].
Sierra is a very loving and caring girl. She is also determined and very persistent. She is very protective of her brother, and is the only person he will listen to about leaving work when he is ill.
In her younger years, before coming to Sodor, Sierra was shown to be very insecure about her outer beauty.
