Another trip to LTT

Got an opportunity to go to LTT (Lokmanya Tilak Terminus) last evening. My parents were traveling to Ernakulam. I was lucky to get tickets for them on the newly inaugurated LTT-ERS Duronto Superfast Express. In fact, this service was introduced only on the 18th of January. As is the case with most other Durontos, there are hardly any stops - in fact, the train travels non-stop to Ernakulam (with only about 5 technical halts - maybe for crew change, etc., but not to pick up passengers).
 
The train's scheduled departure is at 20:50 from LTT,  and I reached there about an hour earlier. The rake (brand new LHB coaches, but with a "fractal" livery - printed plastic stuck over its original paint)  was spotlessly clean. I could see the inside of the luggage compartment - it was all shiny stainless steel. The service crew of the train (in uniforms) were busy loading bottles of water and other stuff onto the train coaches. There were 1st AC, 2-tier AC, and 3-tier AC coaches. And, of course, the pantry car and a hot buffet car as  well.

The loco was still not attached. After I  got my parents settled, I went off to the front of the rake to see what I am always keen to see - the coupling of the loco to the rake. There was no activity related to the coupling. I sat down patiently. When it was about 20 minutes to departure, I could hear a short horn - a typical WDM3 / WDP4 horn. A couple of khalasis turned up with a wireless radio and the work gloves. One of them asked the other whether it was an AlCo, and the other replied in the affirmative. Moments later, the Kalyan loco shed WDM3D #11254 had arrived on the same track as the rake. A couple of hand signals later the loco waited about a few hundred meters away. The khalasi jumped onto the tracks, adjusted the coupler of the rake, clambered back up onto the platform. Meanwhile, a handful of engineers arrived at the spot - making checks, giving comments, studying or whatever else they seemed to be doing. I got a feeling that this unusual visit by the engineers at the everyday event of coupling  could have been because of the presence of the LHB rake at LTT. (Usually, only Rajdhanis and Durontos have these coaches - and this might have been one of the first services with LHB coaches at LTT).

A few more hand signals later, the loco was moved very gently to be attached to the rake. The khalasi jumped back again, and coupled the rake - air brake pipe as well. Another one did the checks. With all final checks in place, the pilot started the compressor, and all was well.

A few minutes later the engineers were in the SLR coach checking out the diesel generator sets, the brake van, etc. Another 10 minutes later, the train revved up, and departed  - albeit a few minutes later than its scheduled departure time.

Nexus S : my first Android

Received by first Android phone (a Nexus S) a few days ago. I have been playing with it, and trying to get a hang of whether it is a good competitor to the iPhone. Though I love gadgets, I have been consciously trying to avoid adding to the e-waste. So, while I used my first mobile for about 8 years, the Nokia that I current use is just about a year old. I do not intend to make the Nexus S my daily phone, but more to use it as a developer's phone. It still does not have a SIM card - I use it via the WiFi setting up my Windows 7 as a virtual access point.

From whatever I have read, it has a 1GHz processor, and until now the phone and the apps seems to be quite a pleasure to use. There are few grouses regarding the placement of the home buttons / rocker buttons, but I'll reserve that for a later post.

Until now (like my brief iPad experience outlined in this post), Android seems to have a large number of games / entertainment apps available. So, off I go back to the phone to have some more leisurely Sunday fun.

WDM2 Interactive

One of the fun things to do is to play around with this Flash animation created by Sheeju Chandran available at IRFCA. Depending on your browser / Flash plugin  version, you may have  to right-click and choose "Play" and select the "Interactive Technical Diagram". Among other useful information, the parts of the WDM2 and its inner workings (obviously a simplification) can be viewed. Check it out, and don't forget to try out the short and long horns, and the air compressor and release.
