###### Unit-2:  Module - 2

Geometric design of railway track: gradients, grade compensation, speed of trains on curves, super elevation, cant deficiency, negative super elevation, curves, widening on curves.

###### Unit-3:  Module - 3

Railway traction and track resistance, stresses in railway track – rails, sleepers, ballast. Points and crossings – turnouts, switches, crossings. Track junctions – types, splits, diamond, gauntlet, scissor crossovers. Railway stations - requirements, facilities, classifications, platforms, loops, sidings. Railway yards – types, required equipments in yards. Signalling and control system – objectives, classification, Interlocking of signals and points.

###### Unit-4:  Module - 4
