I love my BWT, too.
But, sentimentality aside, it's always been an ill-fitting model for a transport of that size, and really does look like a scaled-up Zoner freighter. This model, however, is definitely on the road to looking like the BWT should look. It's never made sense to me that the BWT carries more than a Train but the Train looks like it has so much more cargospace! It's paradoxical, almost.
(Perhaps the current BWT could be scaled down into some Zoner-specific freighter if this model here is actually nominated to step up to the BWT place.)
