Ernie 1 is Ernie's track inspection vehicle. He uses it to get about the Underground on his daily rounds and on his tour of the stations.


Ernie 1 is painted yellow with hazard stripes. The Underground logo is displayed on the front and sides of the vehicle. The name of the vehicle is written on both sides in black.


Ernie 1 appears in every episode except Elementary, My Dear Bakerloo!, Bon Appetit and The Wreck Of Sea Shell Bay.


  • In most publicity photos, Ernie 1 is depicted with a seat in the cab, but has never been seen with one in the show.
  • Whenever Ernie starts or stops Ernie 1, it always makes a distinctive "beep, beep" noise.
