It's not your standard building project – but they are not your typical building team.

More than three years on since the Tauranga Model Marine and Engineering Club started work to expand the Palmerville rail circuit at Memorial Park, the project is nearing the home straight.

This morning is the official opening of the extended miniature ride-on railway line at Memorial Park - big news for all children in the Bay, say organisers.

Mayor Stuart Crosby and Bill Holland, chairman of TECT, will officially open the extension at 9am.

Guests will then ride the extension on a special train and then attend a morning tea at the rowing club.

The celebration will continue over the weekend with visitors from model engineering clubs throughout New Zealand until Sunday afternoon, giving them the opportunity to run their trains on the new track.

Later on today, people will be gathering in Red Square to protect against TPPA from 1pm.

Tracy Livingston says TPPA poses an enormous threat to NZ's ability to regulate for itself, and gives foreign investors and multinationals new rights to control our laws.

'This could mean losing the ability to regulate our workplaces, our environment, our health and education systems and much more.”

Everyone is invited to attend the rally and show their support for the cause.
