In the TV series the flying kipper varies in what kind of wagons are pulled. In seasons 1 and 4 both had one utility van at the front. The rest of the trucks were then just single ventilated vans (both types), the LMS ventilated van and a grey BR 25 standard ton brake van. Season 5 did not have a utility van at the front, just the vans and the same brake van previously mentioned.
If you want the items in a TOMY / TrackMaster scale, then it would be best to have 6 troublesome vans and one brake van, all grey.
If you want to make this train out of engine 3 packs you can get a troublesome van from Arthur, Edward, Henry (Plarail, T-03 and TS-03 only) and James (Plarail, T-05 and TS-05 [1st edition, 2012 - 2014]).
As for the brake van, either get it from Stepney or Emily (Plarail, T-36 only)
