Before 2016, timetables and other publications related to HSL commuter train services were produced in co-operation with VR, and so commuter train timetables before 2016 (roughly) can be found on the VR page.
Helsinki-Järvenpää (R, T) (D trains did not run over summer 2023 due to work at Tikkurila)
Helsinki-Kauklahti (E, L, U, X, Y)
Helsinki-Kauniainen (E, L, U, X)
Helsinki-Kirkkonummi (L, U, X, Y)
Helsinki-Leppävaara (A, E, L, U, X, Y)
For some reason, the validity period had only been changed on the first page of the Winter 2022-2023 timetables.
