In the centre of the quarter, which is formed by the Sadovaya, the Leontievskaya, the Srednaya and the Pevcheskaya Streets, is an electric power station, the first erected in Tsarskoe Selo, and the water-tower.

The Pevcheskaya water-tower was erected in 1887. Its reservoirs are filled by two steam pumps with a capacity of 10,000 vedro (buckets), an hour. The water used to be pumped from the Krestovy canal or the Kukhonny (Kitchen) pond in the Alexander Park. At the present time however the reservoirs are filled directly from the new Orlovsky water works. The reservoirs of the Pevcheskaya tower are connected with those of the Orlovsky tower by 8 inch pipes. The Pevcheskaya tower supplies chiefly the town of Tsarskoe Selo; the Orlovsky that of Sophia.

In the buildings, belonging to the Pevcheskaya tower, there is also the town electric power station. The electric light and the water service were both: introduced in 1887. The steam pumps were so adapted as to be able at the same time to work the dynamos. As has been already mentioned, Tsarskoe Selo was the first town in Europe entirely lighted by electricity. At the present time the original organization of the town electric station has been replaced by a new mechanism, which works independently front the steam pumps. It consists of two generators of alternate currents, with a high tension of 2000 volts and horse power one of 500, the other of 225. In addition there is one steam dynamo of constant current, 720 volts and 225 horsepower, specially for the lighting of the streets. In the town there are 195 lights of 8 to 12 amperes, fixed to or suspended from iron ports. The original arrangement for lighting the streets was carried out by the engineer Pashkov, the first alternate-current generators, Gantz and Co. system, were set up by the engineer Grinevich; while the new mechanism was put in by the engineer Shvede. At the present moment there are more than 400 subscribers to the electric station.

A few steps from the corner of the Srednaya Street along the Tzerkovnaya, at the corner of the Malaya, stands the palace electric-power-station. After the coronation of Their Imperial Majesties in 1896, anticipating a prolonged stay of the Court at Tsarskoe Selo, the building of the palace station was begun. The building was erected by the architect Danini in the English-Gothic style, while the mechanism was put in by the engineer Shvede. The station has five steam boilers, two triple expansion engines of 350 horse power, immediately connected with the alternate current generators of 2000 volts, one compound engine and generators of 40 horse power, and one steam turbine generator of 500 horse power. This station lights the Alexandrovsky, the Bolshoi (Great) Ekaterininsky parks, the Reserve palace, all the palace buildings and the barracks of H. M.'s own Life Guard and Infantry regiments.

On the other side of the Pevcheskaya Street begins the garden of the Lyceum. At the corner of the Tzerkovnaya, opposite to the garden, on the right side of the Srednaya, is a three storied house, occupied by the lower servants of the palace. At the beginning of the century some workshops and a stone almshouse were erected on this spot. At the opposite corner stands a charming villa, belonging to the widow of the author B. M. Markevich. Its architecture is a typical example of the style of the end of the XVIII century. The last house at the corner of the Dvortzovaya Street belongs to the Countess Shuvalov, its interior is luxuriously decorated in the style of Louis XVI. The Srednaya Street ends at the grate of the Alexander Park.
