Ahh... ok...
So:
- you saw Aster kits (very expensive live steam locos)
- you like LGB
- you wondered if LGB made kits.
heck no...
Two completely different worlds and reasons... the Aster kits exist mainly to let a hobbyist do the mechanical finishing and assembly in a complex live steam loco.
There is no such thing or need or saving in an electric loco, i.e. the drivetrain is simple and does not need machining or anywhere near the assembly effort.
The only kits were rolling stock, either traditional wood and metal casting kits, and a few manufactures sold unassembled plastic kits, I think MDC in 1:32...
Sorry, there is no way to save money, unless you build the chassis, and/or build the superstructure... you can save money that way, but that is not kit building, that is scratch building, takes a lot of talent, or a 3d printer or both.
