Visited on April 3 without charging.
The chargers are in the long-duration P+R parking, you need to take the eastmost entrance, not the one to the kiss-and-ride.
There's a long row of charging stations along the main road. It starts with Mobility, then SBB eCharge, then a bunch of private chargers, then a bit of space before the old regio energie solothurn charger.
I see in older picture that those used to be all private parking spaces. The 4 for SBB eCharge have received new numbers 27 to 30, marking them as public P+R spaces. Just ignore the fact 27 to 30 already exist to the right of the other charging station 🤷♂️ I guess it doesn't really matter anymore as payment is exclusively through plate number in the SBB P+R app.
New space 30 has a sign "Nur für Mitarbeiter Caffe Spettacolo" but I assume this is a leftover from the old parking plan. There's also a pile of old signs behind the chargers, that probably previously labelled those spaces. It's been a while since the remodeling now, you would have thought someone would clean up that mess.
I don't know exactly when those new chargers were put in service. They were already listed in December 2025 on the SBB website, but could have been there much earlier already.
