Nice pics! P1M color is great along with the solid looking cowcatcher.
Single DP1 can haul Seshadri right? Why twins? BZA-CCT is not such aggressive schedule to be maintained.
What's the max speed allowed for P1 and this modified P1M?

A single DP1 will struggle with the 21 coach load. The DN Seshadri towards BZA manages it's punctuality well, but the UP Seshadri to CCT struggles with punctuality as it is usually delayed at BZA. The twins help reduce the delay, which would otherwise blow up if a single DP1 is used.
They are cleared for120kmph, but due to some ride quality issues, usually run at lower speeds. I've only ever checked the speed on the SLO-CCT stretch, where it touches about 100 kmph, but I have experienced faster runs on the main line.

Observations
1. Impossible to REGULARIZE it. Need to improve infrastructure , remove PSR TSR , then only possible to regularize.
2. MTJ TKD needs to be given 150 clearance . WCR must also ttry for 150 clearance in RTM MTJ .
3. Dual WAP5 have awsome acceleration but struggle in rough terrain .. BRC RTM struggles to maintain 90 average speed.....needs improvement.
4.
...
more...
Signalling technology inbuilt in loco is needed for ontime running in FOG.... Inaugural run struggled in Mumbai Fog.
5. LHB rakes struggle in curves to maintain speed. Tilting TALGO type rakes can give better performance and reduce running time to 12.30 hours

Doesn't a single WAP5 touch 160 for Gatimaan? So for this longer rake (6 extra coaches), couldn't they just use the same single WAP5? Because its not like too many stops are there, where quick acceleration after halt is required so they had to use dual WAP5s. It gets pretty much unhindered run throughout.
Also what speed can WDP4 do with this rake?

Re# 2552719-7            Tags   Past Edits
There are several reasons:
1. Potential future upgrades - A single WAP5 can definitely haul a 18 coacher at 150 kmph, but longer rakes ( like the existing BCT Raj for example) cannot reliably maintain such a schedule with a single loco. The twin WAP5's will be necessary if the rake length has to be increased.
2. Better acceleration and braking - Trains take a lot of time to accelerate at higher speeds. While a WAP7 or a WAP5 can accelerate very fast at lower speeds (<110kmph), beyond that they will take considerable
...

time to accelerate from 110 to 130 and above ( In this case, WAP7 will struggle even more at higher speeds). So, even slowing down from 130 to 110 and accelerating back will cause delays in this schedule. The twins are mainly being used to ensure that lesser time is wasted in the high speed sections. (At lower speeds, twins or single doesn't make much difference). Also, twin locos provide more braking power. So the train does not waste time in deceleration and can run at MPS even if it's very close to the next halt. Essentially this helps the train behave more like an EMU.
3. Reliability - BCT Raj was downgraded to a P7 link after the P5 link was observed having problems in wet conditions on graded sections. While this problem has largely been tackled, they are still hesitant to upgrade it back to the P5 link. Twin WAP5's will negate these issues effectively, and they will also be more reliable in that, even if one of the loco fails or struggles, it can just be turned off and the train can continue it's run with minimal delay.
A WDP4 can handle such a run, but it would need utmost priority. IT won;t be able to cover up delays if there are too many PSRs/TSRs. Diesel locos inherently take a longer time to accelerate, and more so at higher speeds. So, if there are too many speed restrictions, a DP4 will struggle to maintain this schedule.

Nice Explanation! Thanks.
Just curious, comparatively speaking:
1. Can a WDP4 run at 160 with say a 22 LHB coach train?
2. What's the max permissible speed for WDP4 by IR?
