for Indian Railways in 1970s and large number of Freight and Passenger Electric Locomotives of Indian Railways are equipped with Stone India Pantographs. The high speed Passenger Electric Locomotives as per ABB design introduced in 1980s by Indian Railways are mounted with AM-92 Pantographs of Stone India make. Pantographs used in the Rolling Stock for collecting current from the Overhead Equipment are manufactured as per Faiveley/France design in various models of AM-12, for Freight and Passenger Locomotive application, AM-92 for High Speed Electric Loco application and AM-18B1 for DC traction and AM-18B2 for dual voltage application (AC/DC traction).

Now from the above Discussion of Stone India The following can be ascertained:
WAP-7 & WAG-9 is fitted with AM-92 Pantograph
Conventional Loco are equipped with AM-12 Pantograph
WCAM Series are equipped with either AM-18B1 or AM-18B2
Now what is the Pantograph of WAP-5 ?
Ans: WAP-5 use a Seperate Pantograph altogether which is named as WBL-85 Single Arm Pantograph. This Pantograph has very less failure rate than AM-92 used in WAP-7 & WAG-9.
Why?
As because, AM-92 is a Spring Operated Pantograph whereas High Speed WBL-85 is and Air Operated Pantograph(Re# 1551874-47)
For more details of WBL-85 High Speed Pantograph of WAP-5 please refer the following PDF Link: click here (It's a 56 Page PDF Document about WBL-85 High Speed Pantograph)
Recently we have a AM-92 Pantograph Issue with LGD WAP-7 near Dasnagar hauling 12859 Geetanjali Exp.(Blog Entry#1551874) If WBL-85 Pantograph are used in WAP-7 like WAP-5 then I think Pantograph Failure can be avoided to a Large Extent.
The 56 Page PDF Document about WBL-85 High Speed Pantograph is attached with this blog for Ready Reference.
You can find video of WAP-5 with WBL-85 pantograph if you search in Google.
