ABSTRACT: The tests described in this report were carried out by the Transportation Test Center to verify the newly constructed overhead catenary system on the Railroad Test Track (RTT) and the pantographs to be used on it. The data produced included height and stagger measurements in support of the construction, also pantograph and catenary data up to speeds of 120 mi/h. The experimental techniques consisted of running specially instrumented pantographs over the catenary which was isolated and grounded (dead line). The TTC pantograph test car DOTX 211 was used to carry the pantographs. The results of these tests showed that instrumented pantograph techniques can successfully be employed in support of catenary construction. The results of the high speed pantograph tests showed that the new style 5 catenary proposed for the New Haven to Boston section of the Northeast Corridor has much improved performance over the existing catenary designs. It was also found that the dual stage Faiveley pantograph performed better than the single stage Faiveley. It was concluded that the complete RTT catenary installation was suitable for operating speeds up to 120 mi/h.
