Cleaner air means higher costs for CT Transit

NEW HAVEN, Conn. -- As technology is continuing to improve and develop, so is that of buses. With the new parts and machinery constantly being updated, more time, money and hours have to be spent on maintaining buses.
“Once upon a time the bus was a plain vanilla vehicle that had a diesel engine and old fashioned technology with no other electronics on it,” said CT Transit’s General Manager in Connecticut, David Lee. “Today buses have more sophisticated engines. Engines that have to comply with environmental requirements.”
Lee said now all buses have electronic controls for diesel particulate filters that are designed to reduce the black smoke seen from most diesel vehicles, which shows the complexity of the vehicles compared to what they used to be.
“The cost to maintain a bus today – even a brand new bus – is partly a reflection of how complicated the technology is and that is also reflected in what you are seeing in the trend,” said Lee.
Michael Volpe, CT Transit’s New Haven maintenance supervisor, said meeting the Environmental Protection Agency’s guidelines and laws is challenging to meet the requirements.
“We have more hybrid models now and they are very complex to work with,” Volpe said.
Adding technology is helping to improve the environment, but Volpe said it creates more complex maintenance work for him and his team.
Another challenge for the maintenance workers is that public agencies are required to go through competitive procurement, which means CT Transit writes a specification for what they need and they have to put it out for bid and the lowest bidder wins.
Although it seems as though this would make it a cheaper and easier process for CT Transit to go through, it does have its own problems.
“Bus fleets go through stages of having some bad buses,” said Lee. “Because they are not all made equal, so it could have been that we had some problem children in the fleet.”
This rule means that CT Transit has to train mechanics to maintain different bus manufacturers and new technologies.
The company will also need to have different parts in stock for the several manufacturers they use, which makes it more expensive and harder to maintain than if everything was fairly uniform, according to Lee.
The inspections for the CT Transit buses have become much more rigorous with the buses coming into to get checked every 3,000 miles, said Lee.
Volpe, however, said the buses are being inspected every 1,500 miles in New Haven.
The increase in cost on vehicle maintenance in New Haven from 1991 to 2012 was almost $4.3 million. However, the total budget has also increased every year since 1996, except from 2009 to 2010. Therefore, the total percentage of the budget spent on vehicle maintenance has remained fairly constant.
For example, in 1996, 22.2 percent of the total budget was spent on vehicle maintenance, and 19.1 percent in 2012. These numbers show that while the numerical cost has increased significantly in these years, the percentage of the total budget spent on vehicle maintenance has actually slightly decreased.
The cost of maintenance has increased from 1996 to 2012, but the total percentage of expenses of CT Transit has not. Part of the reason for that is that between 2004 and 2012, the fleet got bigger, according to Lee.
“But put some strings on that such as the useful life of a bus being 12 years,” said Lee. “So, in theory, every bus that you see on the streets is less than 12-years-old. But often buses have had to be kept in service longer.”
Lee said that currently the oldest bus in the fleet, that just about to be retired, is a 1996 vintage bus. This means it is 6 years older than the predicted useful life of a bus.
All buses in the United States are purchased with 80 percent federal grants and the state has to come up with the 20 percent match.
“This automatically requires more maintenance,” said Lee. “Spending the most money on old buses and maintaining them because the cost of new buses is not in our budget. Because that’s a capital cost, not an operating cost.”
