help me sort this out

I'm not entirely sure what mods are on Spencer but my Gorden is 3v (x2 AA's in the tender) and fitted with a hyperdash 2 motor, he's in this video towards the end, James is fitted with a hyperdash2 motor but is powered with its original 1.5v C cell battery) The biwaka and dd51 and c12 (with the red wheels) are standard motors ( but both have different types of transmissions) and the salty is standard motor too but has the typical flat drive unit used in most trackmaster locos. There's also the White hypercity bullet train which is a standard plarail 2 speed drive unit, but 2 speeds are pretty quick right from the off! The only thing with the two speeds is that they tend to be bullet type trains and I like steamers!
