Series 4 includes one shuttle event from Fillmore to Allen. The event was taped on March 30th, 2025. The series began on July 7th, 2025, and ended on July 25th, 2025. This shuttle event is part of a series of weekend closures involving work on the fire alarm systems, as well as a major repaint at Memorial Park Station. This marks the first season to use the term "Series," following the December 2024 Service Change for Ruben Aparicio Productions.
