Amateur Work

Annotation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In the construction of frogs and switches, care must be taken to have the points and joints well smoothed? Off, and the relative parts securely fast ened together. As far as possible, in keeping with simple' amateur construction, the track equipment will follow closely the designs in use on the standard railroads. In Fig. 1 is shown a section of double track in cluding two split switches and two single frogs. Since this is designed as a third rail system, it is necessary that the third rail should be mount ed on either side of the track just outside the rail.' This system, while requiring about double the quantity of third rail, is far better than the single rail especially where switches and frogs occur. If the car is moving slowly over these places the current may be entirely shut off the motor and it will come to a standstill.
