network 30 the transition device 100 is ecp and wdp equipped and is responsible for receiving itc network commands 30 and translating them into mu commands 40 and train brake pipe commands 50 to the conventional trail 12 in fig2 the first locomotive consist lead consist includes conventional lead locomotive 13 and a transition device 100 the convention lead 10 is neither ecp nor wdp equipped and although responsible for controlling the propulsion and brake systems of all the locomotives and cars within the train is incapable due to the electronic configuration of the train therefore the conventional lead locomotive 13 requires a transition device 100 to receive the local mu commands 40 and train brake pipe commands 50 and translating them into itc network commands 30 to all cars and locomotives within the train the second locomotive consist includes itc controlled 14 and itc trail locomotives 11 the itc controlled locomotive 14 is responsible for receiving the itc network propulsion commands 30 and relaying them to the itc trail locomotive 11 in fig3 the first locomotive consist includes a conventional lead locomotive 13 and a transition device 100 and functions as described for fig2 the second locomotive consist includes a conventional trail locomotive 12 and a transition device 100 and functions as described for fig1 as illustrated in fig4 and 5 the transition device 100 interfaces the conventional locomotive with the itc network 30 via the mu interface 40 the mu interface 40 includes mu propulsion control signals commands 46 and mu pneumatic brake signals commands 47 the mu propulsion signals 46 include traction as well as dynamic brake commands for the propulsion system the transition device 100 is connected to the itc network 30 and provides itc network commands 38.
