The Iași city is partly built on hills, and the tram network reaches, on certain portions, large slopes.

The steepest grade on the entire tram system is 8.8 percent,[4] on the line between Târgu Cucu and the intersection with Tudor Vladimirescu Blvd.

(Cinci Drumuri-Pădurii) towards the Tatărași neighbourhood, one of the steepest gradients on adhesion railways in Europe.

[5] The CTP fare system, jointly with the Iași Metropolitan Public Transport Association (AMTPI) fare system, accept tickets, transit passes and card payments (either direct or through a smartphone application).

In 2018, the payment options were modernized and paying through an app was made possible - by using a third-party application and scanning QR codes that are available in multiple points in the vehicles and on the side of ticket kiosks in most stations.
