I think the phrase 'chalk and cheese' would be an apt description of the difference.
The Lima sports a classic noisy pancake on one bogie with iirc two axles driven. Iirc there are pickups on four wheels?
The new model sports A 5 Pole Double Flywheel Motor Driving 4 Axles with All Wheel Pick Up
While not as good a puller as the 071 the new 201 is an entirely smoother beast than its Lima relative.
