I came across this photo and I did already know what it was about but I had to check. There aren't trams now in Napier Street, Essendon but here is a line up of trams in Napier Street.
There was a siding in Napier Street. Sidings are used mostly for special events and Melbourne still has sidings for trams, where trams are stored with a driver ready to move people after the end of a sporting event. There is one for Caulfield Racecourse, the Melbourne Cricket Ground, another at Docklands for the sports stadium there, The Showgrounds, The Melbourne Sports and Aquatic Centre and the Grand Prix. There is also one in my street St Kilda Road near the city where defective trams are parked until they are recovered by a break down crew and taken back to the depot.
But the Napier Street siding has gone, I think in the 1990s. It serviced what is described on the map as the Essendon Cricket Club ground but better known to some as Windy Hill, once the home of the Essendon Football Club.
The siding was centre in the lower half of the map, maybe 200 metres from the footy ground. Note it is close to Essendon train station, surely a preferable way to get to the city and find your way home from there.
Trams lined up in Napier Street ready to take the punters home from the footy ground after the siren sounded.
Google Street View shows the same three buildings are still there, and the single storey building next to them. My curiosity about Napier Street is sated, but I did note the paving on the road shows the centre of the road has different road paving to the side, the centre being where the tram tracks were removed or covered over.
