12V Starter Set
from 8 years


One year after the initial release of the new system, this set was released as an addendum to the range of 12v starter sets. This starter set was designed to be more affordable than the existing start sets, 7730 and 7740. But as a consequence, the set was reduced to a minimum of required parts, with only one single minifig, a circled track without straight sections, and many basic bricks. Even the seats are placed on square 2x2 plates, while all passenger seats from the existing passenger cars are placed on round 2x2 plates.

The A-model is designed as a railcar, which is a self-propelled railway vehicle designed to transport passengers. It consists of 3 coaches with a drivers' cab at either end of the train. For the design, LEGO leaned heavily on the succesful design of the flagship of the previous year, 7740. As usual with passenger trains, there are lots of doors and windows. And of course the roofs can be removed. Despite being relatively small in size, the set evokes a small suburban train shuttle service really well, and its lack of weight means that it really whizzes along when you crank the power up[1].

In Dutch catalogues, this train set is dubbed the Red Rider ("Rode Rijder").

This is the set to be equipped with the lights kit 7861, in fact so much that this set featured on the instruction leaflet of set 7861 for years.


The B-model represents a happy little steam engine with tender, a passenger wagon similar to 164, and a little platform.
