The tram has just operated on the segment of unconnected 40 meter-long track entirely visible in this photo to the benefit of visiting railfans. Don't miss the 5 mph speed limit traffic sign ;)

Трамвай только что проехал на радость приезжих трамвайных фанатов по участку отрезанного пути длиной 40 метров, полностью поместившегося в данный кадр. Не пропускаем знак ограничения скорости в 5 миль/ч ;)

By 2022 the shed is partially dismantled. The shed is on the left, the modern tram depot is straight ahead:

К 2022 г. ангар частично разобран. Слева виден ангар, прямо находится депо нового трамвая:

> As demonstrated in this photo the car was fully operational.

This is, as far as I understand, still the case (in 2022).
In 2019 the tram was much closer to the real tram network than it is now. Besides those few meters back and forth, I don't think the tram has ever actually run on Tucson's streetcar network.
