Dear Friends,
If you look at the Loco Picture WAP-7 written in hindi in the Loco Body... of 30455
Now this loco should be printed as wap-7i instead of wap-7
This...
more... Loco has IGBT technology
SL NO: 403
Loco Class : WAP-7
CLW NO: TPP 255
Loco no: 30455
Allotted Shed: HWH
Zone: ER
Dispatch Date from CLW: 30.03.2016
The Full IGBT Loco List is annexed with this post for reference by clw as on 3rd June 2019
Previously a class named wap-7i was introduced when IGBT Locos were turned out from CLW that system mainly followed to distinguish those Locos from the GTO ONES.
But as now GTO Loco production has completely been stopped by CLW & other Units only IGBT is produced so I think Railway thinks that no need to distinguish IGBT P-7 as a seperate Loco class wap-7i so they continue with WAP-7 which now means IGBT P-7 as well as earlier GTO P-7 too.
