Why 3-Phase Loco Production is SLOW in CLW?
Ans: CLW had planned to deliver more 3 Phase Loco’s but due to inadequate supply of electronic components by various companies they had to slow down the process of production of 3 Phase Loco’s
(As replied by Dy CEE, CON, (CRJ))
Now I think this Problem is solved and from the coming Month we can see ONLY 3-Phase Locos will be turned out by CLW as already announced by Mr C

Temperature Sensor of 3-Phase Locomotive(Made by Crompton Greaves here)
3 Static Converter of IGBT Based 3-Phase Locomotive
4 Water Cooled IGBT Modules replacing GTO Thyristors now(Image 4,5 & 6)
Advantages of IGBT over GTO:
Earlier when a 3 Phase Locomotive would become dead, the Entire Bogie(Forum Please Note that "Cab-1" of the Loco is referred as "Bogie 1" in GTO and "Cab-2" of the Loco is referred as "Bogie-2" in GTO)would not work. Now with the help of IGBT technology even if one motor becomes dead, with the help of computer electronics it can be isolated and the Locomotive can still be made to run with the help of the other motors. This is one of the added advantages of IGBT over GTO in 3 Phase. Water Cooled IGBT module that is replacing GTO Thyristors. Basically what we see in today's G9/P7/P5 as suffix "i" is nothing but these semiconductor devices that have replaced the old GTO Technology.
Advantage: Better Switching, Fast Response .In Locomotive if a motor fails, the entire bogie need not be separated and the particular motor is separated using this technology.The IGBT Modules are made by Bombardier and they are imported from Germany and assembled here in India.
Machine Room Components of a 3-Phase Loco:
The machine room of a 3-Phase Loco consists of :-
1) Scavenge Blowers (A cenrifugal filter panel where contaminated air is removed via a scavenge flow system).
2) Transformer
3) Machine Room Blower
4) Oil Cooling Units (transformer/converter)
5) Traction Motor Blowers
6) Single phase 415/110V auxiliary circuit
7) Vigilance Control Module
8) Pneumatic Panel
9) Line Converter
10) Auxiliary Converter
11) Oil Pump and fan
12) Static convertor
