Its the train Henry pulls and how he receives his new firebox. It explains why he looks the way he is now, in episode "The Flying Kipper". He is seen pulling it again in seasons 4 and 5, with Duck colliding into the train from behind (S4) episode "Fish", and Henry being sunk in shallow water (S5) episode "Something in the Air".
The flying kipper does appear later in the CGI seasons too, but who even cares about what came after season 7.
Also side note: in the railway series the vans are all identical and all painted light orange brown, the brake van is still grey though.
