Thats an early production pic of Dapols 66. They have improved it further since its been released, and the Freightliner version is even better looking
This is now the standard we are expecting from Bachmann and Dapol, and the soon to come 60 and 57 models indicate it IS the norm.
However in response to your initial question jamster, the 37 above does not have lights . As this is a re-released Farish model and not a new Bachmann/Farish model, it is too the same spec as before with little improvements.
The 60 and 57 will have working directional lights though, and optional couplers like the pic above, as well as etched grills instead of molded/painted ones.
