There were MS TN EXP and NCJ GUV EXP. Subsequently NCJ GUV got extended to MDU. Then MS TN and MDU GUV got integrated into a single train. Thus making this train as the longest same zone train of SR.
Now some one is asking for avoiding NCJ itself?!?
I would say that it is better to split this train into 3 distinct trains:
1....
more... MS GUV express via TPJ DG PGT,
2. MDU GUV via SCT QLN ERS and
3. MS TVC via TPJ MDU TEN NCJ.
