The circuit I posted functions properly with any reasonable train speed past the magnetic sensors, including stopping dead center on the sensor. (The sensors are Cherry Electric MP201801 which are almost perfect for layout use). The latching relay is a Panasonic DS2E-SL2-DC5V. This is a PCB mount DPDT with two 5V 139ohm coils. Putting a 120ohm resistor in series with each coil keeps the current well within a tolerable range for continous duty. I have used this relay on other projects and it holds up well.
