Engine 60 has moved to 24 Station as a second Engine from what I understand, or they just jump stations still during rush hour and depending on call volume.
Another Emergency Response YouTuber was saying (from their father who's in CFD,) that they will no longer be calling Aerials "Aerials" soon. Instead, they will be Towers or Ladders, depending on if they are a Bucket Aerial or not. For example, Aerial 25, 31, and 19 will be called Towers, and anything like Aerial 1, 6 and 23 etc, will be called Ladders. No idea if this is 100% confirmed, but it's possible.
