Can the DMU's fit under the light rail wire? Assuming they can..couldn't NJT run the DMU's straight though to Hoboken?The DMUs will never operate through the West Shore tunnel, if that's what you're asking. The DMU is about 13 feet 7 inches in height IIRC, and it looks like something of that height could fit under the wires, but don't quote me on that...certainly CRC's double-decker won't, at over 19' 6" tall (which exceeds the height of most bilevels).

So even if DMU's fit under the wire they cannot be run on HBLRT trackage (i.e. assuming that they are capable of taking some of the LRT radius curves).
They will be able to fit under the NEC wires into NYP..assuming the one trip ride is going to happen
what is the height difference between the two systems?
In response to "Inflating costs of light rail" (Your Views, March 26), I want to clarify NJ Transit's plan to advance diesel multiple unit service on the Northern Branch into Bergen County as an alternative to extending the light rail system north from Hudson County along that route.My response was printed today in the OPINION section of THE RECORD
NJ Transit's goal is to provide Bergen County residents with rail access to both the New Jersey waterfront and Manhattan on a one-seat ride. In fact, I think we have a responsibility to ensure that we do both, in the interest of making the highest and best use of resources to relieve congestion and deliver more service choices for commuters.
Forecasts indicate that ridership is maximized with the one-seat ride to Manhattan. Thanks to the governor's plan to replenish the Transportation Trust Fund, we will have the committed funding we need to advance the Northern Branch project.
With an initial investment of less than $500 million, a DMU-based Northern Branch can be delivered sooner than a light rail system and at a significantly lower cost. This would be due primarily to the ability to operate both freight and diesel passenger trains on the same track. Light rail would require expensive structures in the North Bergen yard to separate the light rail from the freight lines, two separate tracks for the passenger service and the freight service, and the cost of electrification.
DMU service will not compromise freight business or require separation of freight and passenger service. Light rail service would push freight service to evening or weekend hours, creating noise and vibration issues to which residents would most certainly object. Light rail would require bridging over the heavily utilized North Bergen freight yard and the Edgewater Branch freight tracks at considerable expense.
The most important public transit project taking place in New Jersey and the region is the new trans-Hudson tunnel to Penn Station in Manhattan. When completed, the $6 billion tunnel would offer further support for a DMU-based Northern Branch. The project would double the number of passenger trains that can enter Manhattan, offering new capacity for the Northern Branch that can then use dual-mode powered trains and thus offer Bergen County's Manhattan-bound commuters can have one-seat rides to work.
On the other hand, a light rail system would bring commuters only to the Hudson County waterfront and require Manhattan-bound commuters to transfer to ferry, bus or PATH service to complete their trip. A light rail system would be prohibited by Federal Railroad Administration safety standards from utilizing the tunnel.
I appreciate the enthusiastic support the DMU project has received from Rep. Steve Rothman, D-Fair Lawn, and other leaders. It is the right thing to do in the long run to serve the largest market.
The first step toward that goal is providing DMU service from Tenafly to a North Bergen stop on the Hudson-Bergen Light Rail system at half the cost of a light rail extension, completed in a shorter period and with less impact on the communities we serve.

NJ Transit Executive Director George Warrington promised that diesel multiple unit service, which could provide one-seat rides to Manhattan, would bring maximum ridership on the Northern Branch of rail service in eastern Bergen County ("In defense of diesel for northern Bergen," Your Views, April 16).
That anticipated ridership would come only after and if the agency builds the connection to the new tunnel.
Warrington expects a replenishment of the state's Transportation Trust Fund to pay for DMU service. But the DMU project risks loss of federal funds. The DMU's projected ridership is so low that the project will fail to meet Federal Transit Administration cost/benefit criteria.
Warrington expects a speedy completion of the less expensive DMU. But the DMU proposal has already resulted in a more than three-year delay caused by NJ Transit abandoning the completion of the 2001 Draft Environmental Impact Study.
Warrington says light rail would require expensive infrastructure improvements. But the costs would be more than offset by elimination of the expensive DMU transfer station in North Bergen.
He said light rail would require bridging over the Edgewater Branch freight tracks at considerable expense. No new bridge would be necessary for Edgewater Branch freight tracks; they are already located on a bridge that goes over the Northern.
Warrington has great expectations in a new trans-Hudson tunnel to Penn Station in Manhattan. But NJ Transit has not provided any cost estimates for connecting the northern DMU into the tunnel. There is a strong possibility that funding for this connection will never be available.
As currently envisioned, a connection would require a six-mile loop going through Jersey City to Secaucus Junction and back to North Bergen. This may be feasible, but it will result in an impractical routing that would waste both time and energy.
NJ Transit should not bow to political pressures but give more weight for following practical engineering principles in the capital planning process. The only sure step toward the goal of rail service for northeast Bergen is providing direct light rail service from eastern Bergen to Weehawken and Hoboken.
The DMU path leads only to more studies and no rail service at all.
