Single-level cars require longer, heavier trains to move the same amount of passengers as bi-levels, more money spent on maintenance and fuel, and you more quickly max out the system's capacity (both in terms of how long a train can get and how many trains you can run per hour). When it comes to moving as many people as possible, bi-levels are the best bang for the buck.

Buying more single level cars won't increase the capacity by much. Do you even know how old the mbb's are. At least 25-30 years which is a long time. The bombardiers I believe are 10 years younger or something like that. Someone with better accurate info please share it since I don't know the facts like textbook. I only know what I hear. Getting more bi-levels from Kawasaki or a better builder is the better and cost effective way to go. It may sound like a lot now, but on the long run it will pay off.

Actually, the Bombardiers are around the same age as the MBB's, reference http://www.transithistory.org/roster/" onclick="window.open(this.href);return false;

The 3XX Bombardiers were built in 1987.
The MBB's were built in 1987-1988.
The 16XX & 6XX Bombardiers were built in 1989-1990.



I'm assuming all new Bi-Level coaches would have powered doors. Would we expect to start seeing them using them on stations like Salem once we have set's fully capable?

Nah they are planning on retiring them after they aquire more new cars and once they have been accepted into service and work like they should. They are trying to increase more capacity to trains plus the mbb's and bombardiers don't ride that good nor operate smoothly either. Plus they are heavier and move slower than the bi-levels and don't have as much capacity. They are also beyond their useful life too.

Single level cars are heavier than double deckers? They move slower? You really need to start sticking to topics you’re familiar with.

It’s the MBTA, everything has a rubber-stamped 80 MAS for the Commuter Rail, even if it was designed for 90 or 100 or 125 MPH.

The BBD ML II design is fairly bulletproof and has Hi and Low platform access doors,as long as MBTA doesn't add a lot of custom options,
should be a retaliative quick build.
Unless you want to issue a set of Bonds to pay for the cars,CRRC is out if Federal $$$$ is used.

Single level cars are much faster boarding & getting off, and don't have the ADA problems. High level platforms were designed for and work better with single-level coaches - if they knew they were going to bi-levels it would have been a lot easier to stay with low platforms.

Bi-levels are lower weight per-passenger. Do the rules require a certain number of conductors per coach or per passenger?

NJT has no issues with their bi-levels and high platforms. Of course NJT also has auto traps and full length auto doors, something that MBTA has never adopted for some reason, despite the fact that like NJT it has a mix of high and low level platforms.
