could it be that the rail head has lost it profile and is need of grinding and the unit is hunting maybe

could this have been the auto drain valve on the main res tank, this allows any water that forms when air is compressed to be drained off.

fcc do apprenticships at their Hornsey depot

no this is known as tyre roll over, http://www.am.chalmers.se/~anek/research/fatigueintro.html try the abve web as rcf is a long subject.

to answer your question on re profiling wheels at our depot its done on mileage it depends upon whether its a trailing wheelset or a motor coach if there is no flats, cav's, thin flange, high flange or hollow tread to name a few they will be turned to try and catch the rcf building up. if this...

It's at hornsey for Tyre turning.

I used to work at east ham on the 357's and could always tell when the little darlings were not at school by the way the units came into the depot with the windows smashed bless them.

Are there many spies?:D

this is exactly what happens on ac units as for dc unit dynamic braking works by turning the traction motors into generators the voltage is then dumped across resisters the same happens for ac unit in dynamic braking but when the unit is in regen mode the voltage is passed back through the...

regen braking in modern day electrostar units only works when there are more then one unit in the same section. If no other unit is in the same section then no regen braking will take place just dynamic braking. modern electrostars use brake blending using regen, dynamic and friction braking.

a bit of respect for the driver would not go a miss, I know of drivers that have to given up their post because they can not face it again.

this is me first posting be gentle, there is defect book on all FCC units one per unit where the drivers fill in these are then viewed and acted upon at the depot during exam work and then the book must then be stamped and signed. the heaters on the 313's are thermostatically controlled but if...
