- "Daisy come on now, don't be that way. It's Philip. Look at his cute puppy dog eyes and his face..."
- ―Arthur, Philip and Daisy - Meet the Characters!
Philip is an energetic boxcab who works in the Shunting Yard.
Philip was quite enthusiastic to prove himself to the other engines following his arrival. Upon meeting Gordon, Philip was eager to prove his speed, racing the big engine to Brendam Docks before realizing the Gordon never actually agreed to race him! After James' attempt to outdo the little engine backfires, Philip tries to rescue the vain engine, only to have James fall onto his roof.
Philips met Hank at Knapford, quite excited to converse a fellow "Pennsy" on Sodor. The little boxcab got lost in conversation with Hank, neglecting his job of shunting Molly's train. When Hank returned to the Lumberyard a day later, Philip became disappointed when Hank declined a race.
Hank later broke down on his way back, and Philip was all to eager to help out his new friend. However, his ability was insufficient to move Hank, causing the big engine to topple over when the track beneath him shifted. Feeling guilty for his actions, Philip longed to apologize to Hank, but was unable to leave the yards. Utilizing Percy, Philip sent Hank a letter, and the two continued to exchange letters as a way of conversing while apart from each other, developing a strong friendship along the way
Philip also made friends with Toby, whom he originally thought was also a diesel boxcab who also loved racing. The two were actually able to become friends when Philip realized that not everyone has to like the same things to be friends.
Philip is an enthusiastic and energetic diesel boxcab, though not as fast or strong as he thinks, he is always eager to help and keen to impress.
