Commuter Rail 101: A Primer for Startups
Commuter Rail is the fastest growing rail transit mode in North America with new systems starting up all over the continent as legacy systems seek to redefine themselves. This workshop is designed to give pointers and lessons learned to those contemplating the commuter rail arena, organized around the recently released TRCP #200, describing state-of-the-art practices for contracting for commuter rail services.
On Sunday January 12 2020 the 99th Annual Meeting of the Transportation Research Board will hold workshop on New Start Commuter Railroads for North American featuring some the leaders in the Renaissance of Commuter Rail.

New Passenger Rail Rolling Stock Safety Standards Proposed
The current
regulations rely on equipment design requirements which limit application of
recent technology. The proposed new
rules use more performance-based requirements to demonstrate safety in
alternative ways. FRA believes this rule would have a net beneficial effect on
the passenger rail industry and society as a whole.
The technical
criteria are based on established international standards and significant
research and testing both the industry and DOT's Volpe Transportation Systems
Center Codifying the technical criteria would dovetail with alternative
crashworthiness performance requirements FRA established in part 238 for the
front-end structures of cab cars and multiple-unit (MU) locomotives, thereby
broadening application of such requirements to other main structures.

Diesel Multiple Units in 21st Century America
January 11, 2011 | 8:00 am | Room 144A | Walter E. Washington Convention Center, Washington
DC
US public transport officials working with finite resources to build and operate new fixed guideway transit services grow more and more creative every year, finding ways to offer new and expanded services with fixed or declining resources. One creative approach to the development of new urban passenger rail services has been to operate new passenger rail services on tracks shared with light density freight services. Most services have used conventional commuter rail passenger rolling-stock for these services, but in some circumstances this relatively heavy equipment has been inappropriate, forcing officials to look into sharing freight tracks with lighter shorter trains. Some of these trains have been conventional electric light rail cars, but since the turn of the 21st century, five new services have opened using self-powered diesel rail cars (commonly called DMUs) to offer new travel options in Texas, California, New Jersey and Oregon. The Federal Transit Administration (FTA) has termed these new shared track services “Hybrid Rail.”
David Nelson, Tara Blakey and Kay O'Neil Nelson recently reviewed the circumstances and conditions that gave rise to the development of these hybrid DMU systems. They used federally reported data to conduct a comparative survey and evaluation of these services compared with electric light rail and conventional commuter rail services. The analysis finds that the new DMU systems tend to function in a new service stratum between commuter and light rail, serving markets that neither traditional mode is well suited to address
Their analysis finds that the new DMU systems tend to function in a new service stratum between commuter rail and light rail serving markets that neither traditional mode is well suited to address.
- Service Density – At 5,000 to 10,000 annual train miles per directional route mile, the new hybrid DMU systems clearly offer greater service density than similarly scaled commuter railroads but in no case do they offer the higher service densities associated with US light rail services. The hybrid systems generally offer more travel opportunities than commuter rail services but fewer scheduled trains than light rail services.
- Service Velocity – At 20 to 25 train miles per train hour, the hybrid systems tend offer a higher service velocity than light rail but slower one than commuter rail.
- Station Spacing – With 1.5 to 4 one-way route miles between stations, the hybrid DMU systems have a greater average station spacing than nearly all light rail lines and less than all smaller commuter railroads.
- Average Train Length – The typical hybrid DMU train is one or two cars. This is typical of most smaller light rail services and less than all US commuter railroads.
- Passenger Density – The hybrid DMU rail services tend to attract 150,000 to 650,000 annual passenger miles per directional route mile. This is consistent with smaller commuter railroads but less than all but a few light rail services. As these new services mature it is certainly hoped that their passenger densities will rise with the development of the environs surrounding their stations.
- Average Passenger Trip Length - The hybrid DMU systems service typical trip lengths in range of 10 to 15 miles per passenger. Light rail systems all have shorter average length. Commuter rail system average trip lengths range between 15 and 45 miles
- Average Train Load - The ratio of passenger miles to train miles for the typical DMU service is typical 50 passenger miles per train mile, consistent light rail services. Commuter rail average train loads typically tend to be much higher.
- Transport Operations Costs per Train Mile – The emerging hybrid DMU services exhibit train operations costs in the range of $10 to $20 per train mile consistent with most light rail services with similar train lengths and crewing regimes.
- Mechanical Maintenance Costs per Vehicle Mile - Reported unit costs for the RiverLINE, Sprinter and Cap Metro are approximately $4.00 per vehicle mile somewhat above the median for other commuter rail and light rail services. This may be partially due to their small fleet sizes.
- Total O&M Costs per Train Mile - The new DMU services with short trains range between $30 and $60 per train mile. Most light rail services fall in the range of $20 to $40 per train mile. Most US commuter railroads range between $50 and $200 per train mile. The larger and more mature hybrid DMU systems with more extensive service tend to have lower average costs.

History of the TRB Rail Transit Committee and all it's "offspring"
The TRB Rail Transit Systems Committee (AP065) has been working on a project to
record the history of the committee, which also includes information regarding
the origins of the standing committees which trace their roots to the Rail
Transit Systems Committee.
The report, prepared by Dave Phraner, former chair and Emeritus Member of AP065, has now reached a substantial level of completion. But is not yet final. If you are interested in the history of the committee(s) please read the paper, and respond with any comments that you may
have. It would be appreciated it if you could comment no later than Monday, January 6, 2014.
