- “Just because they're old doesn't mean they're not useful!”
P.A. Problems is the sixth episode of the twenty-first series. It is also the 500th episode of the television series.
The Fat Controller bought a new TX-1000 public address system to replace the old ones at Knapford Station, which he sends Edward to take them to the scrapyard. There, Edward sees Reg, who is happily singing about scrap.
Back at the station, the engines and passengers struggle to hear the announcements after the new P.A. System begins malfunctioning, and they all end up very confused. Toby takes some Holidaymakers to the quarry, Thomas takes the quarry workers to the beach, and Percy takes a delivery of pigs to Lord Callan at Callan Castle. Eventually, The Fat Controller realises that his new P.A. system is not working properly, and ironically destroys it after attempting to fix it.
After much confusion and delay, it is Reg who saves the day. Rather than destroy it, Reg had put the P.A. system to good use by attaching it to himself and using it to play music. Reg happily hands it over, and the old P.A. system is returned to Knapford station. Everything went back to normal, except for the workmen who can't stand hearing Reg's singing as one of them covered his ears with two rubbish can lids taped around his head.

- This episode marks Reg's only appearance in the twenty-first series.
- In the scrapyard, a bike, a blue car, and the bus stop sign from Samson Sent for Scrap can be seen. One of Theo's flywheels can also be seen.
- Clips of this episode appeared in the series 5, episode 8 of "Dave Gorman: Modern Life is Goodish." In the episode, Gorman points out that this episode teaches a very good moral about materialism. Gorman then refers to the Fat Controller as "one of them people who wait for the new Apple phones."
- A shortened version of the episode, narrated by Joseph May as Thomas, can be found on the official YouTube channel and the Nick Jr website.
- Throughout the episode, all the teal 7-plank trucks appear to be glowing red on the bottom plank indicating that they were modified from the red trucks.
- When Edward pulls into Knapford Station with the old P.A. system, his siderods slide on the tracks, then start moving again.
- Thomas is heading South instead of North towards Harwick whilst departing Knapford with the Quarry workers onboard.
- When Edward arrives at Crock's Scrap Yard for the third time, the tracks are empty on the left side of the screen. But when Edward blows his whistle to get Reg's attention, a truck full of scrap suddenly appears and it is the same truck Samson pulled in Samson Sent for Scrap, due to the Fat Controller's car being clearly visible inside it. Then it disappears when the workman switches off the speakers.
