Abstract
A read-convert device for use on an electric brake command car of a railway train having pneumatic brake command cars. A control wire provides the electric emergency brake control on the electric brake command cars, while a brake pipe provides the pneumatic emergency brake control on the pneumatic brake command cars. A cut-off portion of the read-convert device connects a regulated source of pneumatic pressure to the brake pipe when an electric emergency release signal is provided by the control wire, provided a switch valve in the cut-off portion is set for electric brake command operation. Accordingly, an electrically-initiated, emergency brake application on the pneumatic brake command cars can be released through the control wire on the electric brake command cars.
