Series 19 experimented with a more traditional drama running time similar to fellow ITV police drama The Bill. Roughly 48 minutes (excluding adverts) and single episode stories instead of the usual Taggart 2 or 3 part stories which could run for 1 hour 30 minutes or even close to 3 hours in some cases.
For series 19, Tamara Kennedy's character Sheila Crombie was promoted to series regular.
Stuart mentions "The hole in the wall" - this is simply an informal name for an ATM.
