The tram has two double-doors in each segment (or four in bi-directional version) to allow fast boarding of passengers, and one extra side door leading to the driver's cabin.

The Škoda 15T ForCity was developed as highly modular; it is offered with up to five car body sections and 50.6 meters (166 ft 0 in) in length.

As the bogies are under articulations and don't interfere with the inner space of the body sections, there is unlimited choice of interior lay-out and location of doors.

On the axle bearings there is a combined, dynamically resistant, primary rubber-bonded-metal-sprung bogie framework.

The swing bolsters have pivot bearings, which facilitate full rotation of the bogie below the body without any limitations.

[1] All bogies are equipped with identical wheels, which have tyres damping rubber pads to minimize noise.

Individual wheel drive on respective bogies secures perfect use of adhesive conditions and ideal ride both in bends and on straight lines.

The traction motors don't use a gear box - they drive tram wheels directly through a mechanically disconnectable jaw clutch.

In selected double-doors area there could be either ramp or lift enabling easy entry for passengers with restricted mobility.

[1] Škoda ForCity won the bidding process of the Prague transport company for 250 new trams in 2005.

During the delivery of the first batch in 2011, the Prague transport company started negotiations with Škoda regarding the installation of air conditioning in the passenger compartment.

It also raised the concern that a 1,000-horsepower streetcar may be unnecessarily powerful and proposed a solution used in the Riga version, which has only three out of four bogies driven.

In the view of the transport company the price of additional air conditioning should be covered by eliminating the first bogie's motors.

Firstly there is issue that participants in the original tender may contest the change and require a new competition; secondly it has to be tested whether the 15T without full adhesion would be able to drive on Prague's hilly network.

[7] In May 2014, due to financial problems for the City of Prague, the Prague transport company and Škoda Transportation renegotiated the contract to provide for four extra years for delivery of the order and for fitting of full air-conditioning and WiFi in the last 125 trams of the order.

A Škoda 15T from Prague underwent testing and certification on the tram network in the German city of Chemnitz in 2012.

The trams are 32.5 m (106 ft 8 in) long and using hydrogen fuel cells to allow service at the parts of the route without overhead electrification.

The trams are two sections long and use supercapacitor and lithium-titanate battery energy storage to allow service at the parts of the route without overhead electrification.
