TNSTC-MDU operates buses mostly in the south TN. It has the most number of fleets than any other TNSTCs. In 2010(till date) Madurai city added around 250 JNNURM buses. The old SLFs that were running in the madurai city were transferred to different regions of TNSTC-MDU i.e., MDU, VNR, Nellai, DGL and NGL. Those SLFs were modified for intercity routes with 3X2 seats.
I spotted the first modified SLF in MDU-CBE route. Personally used that SLF 3 or 4 times. It charges Rs.15 more than the the other buses running in MDU-CBE route. But this guy covered the distance in 4 hrs. In later point of time it took 30 minutes more.
These modified SLFs were operated in many routes like MDU-Cumbum, MDU-Palani, MDU-DGL, MDU-Sengottai, MDU-Tuty, MDU-NGL, MDU-Marthandam, MDU-Nellai etc.,
Now lets come to the new buses. TNSTC-MDU Madurai region added new buses mainly from JNNURM. This JNNURM was partly funded by central and state govts. These JNNURM buses were for madurai city. But few buses were given to DGL region initially, later they were reverted back to MDU region itself. JNNURM buses were SLF buses from both AL and TATA. TATA buses were marcopolo built from their dharwad unit where as AL SLFs were Irizar TVS built. Coimbatore and Chennai got JNNURM buses built from Irizar, Prakash, G.S, Veera Vahana etc., But for Madurai it was a single body builder. JNNURM buses at madurai were branded as “vaigai ratham”.
Some of the JNNURM buses are.,
Madurai region buses started the registration nos from TN58 N 1433 and the latest was a yellow marco with reg no TN58 N 1806. Very few mofussil buses were added to MDU region. To my suprise i havent seen even a single new AL moffusil bus from MDU region. Where as other regions didnt add any TATA bus.
Dindugal Region was one of the major share holder to get the old SLFs running in madurai. It got few JNNURM SLFs initially. Later they were given back to madurai region itself.
Virudhunagar Region was the first region in TNSTC-MDU to start running the new mofussil buses without any formal inauguration. Registration nos started with TN67 N 06XX and the latest i saw was around 065X
Nellai and Nagarkovil region added the new moffusil buses with same design and livery. They look very similar and the only difference is their registration nos.
Note: Will try to update the post with more Pics soon.
