New locos

Geaf 2/2 20601-7
So G = Interesting it’s a loco not a tractor?
e = electric loco,
a = battery
f = radio control.

So no diesel but a hybrid battery and overhead?

The Rhaetian Railway (RhB) will renew its shunting locomotive fleet in the coming years. On 3 September 2018, it signed the purchase agreement for seven new shunting locomotives with Stadler Bussnang AG. The order volume amounts to 21.5 million Swiss francs. The new vehicles are expected to go into operation in 2020. In return, eleven old shunting vehicles can be retired.
The procurement was carried out in close cooperation with the Matterhorn Gotthard Bahn (MGBahn), which has also ordered two new shunting vehicles of this type. In this way, synergies were exploited and procurement costs reduced by around 1 million Swiss francs.

The two railways are innovative in their procurement: the new shunting locomotives are electric-battery hybrid vehicles. They are primarily electrified. If they are used in construction work when the overhead contact line is switched off, in the event of a line interruption or in non-electrified tracks, the auxiliary drive is used. Lithium-ion batteries have now been developed to such an extent that they are also an appropriate alternative to the previous diesel or dual-powered locomotives with diesel and electric drive for shunting vehicles on the railways as an auxiliary drive. The auxiliary battery drive is more environmentally friendly and cost-effective. So far, there are only a few two-force locomotives that have a comparable battery auxiliary drive. With this procurement, the two railways and Stadler Rail are taking a pioneering role. At the same time, the new vehicles will also significantly reduce noise and exhaust emissions. The order for the shunting locomotives was awarded to Stadler Bussnang AG. The new vehicles will be put into operation from spring 2020. The order volume amounts to 21.5 million Swiss francs.
The eleven shunting locomotives that are being retired have reached their intended service life. The most frequently used vehicles became increasingly prone to interference and maintenance. They would have needed a comprehensive refit. However, despite this measure, operating and maintenance costs could not have been significantly reduced.

Point taken... :p

To be honest, I was actually thinking about getting back to it just the other day. :)
