Why do 92 out of every 100 casual railroaders who get serious about model trains buy a Tech II?
	We think it's the unmatched performance of PTC and the rock solid reliability of Tech II. Dependability, features and performance other packs can't match. Having been instrumental in pioneering solid state designs and defining the art of slow speed control, MRC took the next major step with PTC. Here's how it works. As the throttle is advanced, PTC locks on to your engine to define and instantly relay the slightest change in command directly to your loco. It permits your loco to respond without hesitation, coaxing maximum performance from your engine and creating realism that brings railroads to life and turns your loco into a high performance engine. No one else has PTC. All Tech II packs are UL Listed and feature a 5-year limited warranty.
Tech II with Proportional Tracking Control (PTC) ... the best selling train controls in the country The magic of momentum...when a real locomotive is given a throttle increase there is a lag time or delay until the pre-selected speed is reached. The heavier the load of cars being drawn, the longer the delay. Since lightweight model trains can't mimic this delay on their own momentum circuitry is introduced to create this effect electronically. The result is remarkable realism. Both Tech II 1500 and 2500 feature momentum circuitry.
