Looking west towards Chelmsford through Collingwood Road railway bridge. The Station signal box is just through the bridge. The column with a ball on top is a water column. It could swing to the platforms on either side to top up the water in the locomotives. Just left of the ball is an arm, pointing away, there is a leather chute hanging from it. Information from John Newman. See also M580 and M581, M2776-M2777, and M2779-M2788.
