The line is built to 800 mm gauge (2 ft 7 ¹⁄₂ in gauge), and uses the Riggenbach rack system, as modified by Arnold Pauli.
Modern stock uses Strub rack system.

Nowadays, most passenger trains are made up of railcars, the powered car still being positioned at the lower end of the train, and so train compositions do not usually cross Kleine Scheidegg to travel directly from Lauterbrunnen over to Grindelwald.
However, a triangular junction specially built into the mountainside at Kleine Scheidegg allows the train to be turned if necessary so that it can also be used on the other side of the col.
The newest of these trains reach 28 km/h on the steepest stretch.

At peak periods, additional trains can be put into operation at short intervals ahead of the scheduled train, allowing capacity to be optimised according to demand.
This demands an extremely flexible organisation procedure and enormous care and attention with regard to dispatching trains.
Since most of the line is single track, the extra trains display a green disk with a diagonal white line on the front to indicate to station staff and signal operators that there is a train following in the same direction
The busiest stretch of railway runs from Lauterbrunnen to Wengen as this is also used to transport goods to traffic-free Wengen.

The railway operates two workshops at Lauterbrunnen and Grindelwald Grund.
