The French manufacturer CR (Rossignol) made many accessories. Even smaller than the small CR stations are the CR train-stops (or Halte in French). This first one shown is only 10 * 6 * 7 cm. It wears CR number 5 and is very small even next to CR smallest trains.
This next CR train-stop is a bit larger and uses two of the barriers of the previous small one. It is quite a busy place for a small train-stop. It has CR number 11 and is 24 * 7 * 10 cm.
