Train service disruption at Yio Chu Kang at 9 this morning. All passengers on the Marina Bay bound train were requested to disembark and wait for the next train.

Also saw someone recording the commotion using a camcorder...

The noise has always been high there since it a long non-stop sector along a gradual curve. I did notice last week it is becoming extremely noisy that it is nearly unbearable. I think it is the higher frequencies and faster speeds taking a toll on the ageing track without enough maintenance.

By the way, it is next to impossible to find C151As on NSL. LTA/SMRT seems wary of the heavier weight and resulting vibrations of the C151As damaging the floating slabs responsible for the December breakdowns.

Which still doesn't explain the C751Bs.

What do you mean? Are the 751Bs missing too? The C151A and 751B are very similar in design, and possibly specs as well.

Are the C151As missing on the EWL too? I haven't rode a C151A since the December breakdowns.

Not really. I've seen many C151As plying the EWL when I take my bus to work everyday.

I see them in the evening, one after another with one minute frequencies heading westbound.

Why would they run well on the EWL but not NSL?

7Bs are on NSL. What I meant was, the 7Bs and 1As have the same tonnage, so if they take all 1As out of NSL, why aren't the 7Bs leaving too?

The C151A are indeed running on EWL from what I observed, but I think it's more of an operational limitation, possibly because SMRT has decided to stable all the C151A at one of the depots, likely Tanah Merah, probably to have specialised maintenance teams for each type of trains.

I thought I heard in the news that the C151As are supposed to be 5 tons heavier than the older trainsets?

Anyone has the unladen weights of the C151, C651, C751B, and C151A trainsets?

My understanding is C151As are definitely heavier than C151 and C651, but I am not sure if the C751B is heavier. Nevertheless, it won't be easy having two maintenance teams at two sites since only BSD is equipped for heavier maintenance. Anyway C751Bs are mainly serving NSL if you all have noticed so they may just be "spreading the load"

actually, every time I pass Ulu Pandan Depot on PIE, i will always see some C151As parked there. i don't specifically recall 151As in the maintenance building though - they may stable in UPD, but be maintained only in Tanah Merah.

it might be a more complex issue - perhaps, for instance, how a (possibly) different collector shoe design on the 151As complicates the heavier weight of the 151A on the floating slabs to mess up the third rail.

i think the SMRT investigation into last december's disruptions will give us the answer.

anyway, the 151A is probably heavier than the 751B - just going by the increased provision of handgrips and grip poles. the poles are thicker too.

You seem to be missing out the point that stations take up urban space and as a result are randomly connecting the dots to prime locations for new lines.

Only your Northern and Seletar Lines seem viable, but the former's alignment is pretty much taken for granted that it will travel through the eastern/western sides of Woodlands, Punggol, Pasir Ris and Changi Airport.

In any case, welcome to the forums.

Hmm, how is the proposal "missing out the point that stations take up urban space" and a "random connecting of the dots to prime locations for new lines"?

I'm not quite sure what you mean. Urban stations don't have to take up any ground-level space.

I agree. The government have or had plans for Northern and Seletar lines, though the details have probably changed since the 2001 Concept Plan was released. At that time, the Northern Line (often called North Shore Line and sometimes called North Coast Line) was to have its western terminus at Sembawang. With the TSL and a line to JB terminating at Republic Poly, the Sembawang termination plan has probably changed. Your Seletar Line looks even better, but I would expect it to continue to Seletar. The traffic volumes suffice to justify it.

The Eastern Regional Line was announced in 2008 and will cover much of the eastern portion of your proposed Southern Line. Following the DTL3 and the ERL, there won't be any new MRT lines between the CBD and Changi for a long time. It looks like there will be a Holland Line from Tengah to Orchard and perhaps then into the CBD somehow. Until we know more about plans for the Holland Line, it will be difficult to say much about the western part of your proposed Southern Line.

Somehow, there needs to be an increase in capacity between Jurong East MRT Station and the CBD. In my opinion, the best way to meet that need is to extend the NSL southeast from Jurong East to the CBD.

Welcome crosstheroad!

Conceptually, there's nothing wrong with your proposal. With the exception of the Thomson Line, Seletar Line and the Northern Line, which are clearly plucked from the Concept Plan 2001, the others are I guess, "current", and based on the existing traffic trends, and have, not at all, taken into consideration the provisional alignments for the Eastern Region Line, Thomson Line and Tuas Extension. At the end of the day, your proposal is only useful to an extent of establishing where the current heavy traffic corridors not served immediately by rail are.

Your map however, does bring out a poignant possible oversight by LTA - the lack of a rail connection between the Circle, Downtown and Eastern Region lines at two points, one at Marine Parade, and the other in the Bedok area.
