Thanks Dan - forgot that was the term/job classification VIA operates

VIA's plan to reconfigure its Venture sets. Two XL sets and one SX-J set are already complete. (L=locomotive, B=Business, E=Economy, C=cab car.

Presumably there's a technical reason in the L-B-E-C-C-E-B-L set not to do L-C-B-E-E-B-C-L or something, to not put the cab cars in the middle?

@Trackside_Treasure what is this diagram from?

The B car has a coupler on one side which needs to be joined to the locomotive, but is probably not like the external loco and cab couplers

How do they put 2 or 3 B cars together then in the other two layouts?

Two kinds of B cars I guess. VIA isn’t shy about complicating things - look at Ocean and how the couplers create weird constraints especially in the Ren part.

So since it's not enough to cover the corridor, will there be trip cancellations if the LRC's are retired?

Thanks, nice to see it visualized like this!
If/when the shunt enhancers get installed, I wonder if we'd ever see LBEC sets running on a segment like Sarnia-Toronto? I remember as a kid when it was serviced by just two or three Budd cars. (That was my first train ride ever, and I felt cheated that it wasn't a real train. I know rail fans love them, but they felt old and dingy to me even back then in 1980 or 81.)

WHAT?! Via has been running J-trains since before the Siemens trains were even ordered! Combining 50/60 and 52/62 makes a big difference to rail traffic on Lakeshore East in the morning peak. How could Siemens possibly claim that their product doesn't support J-train operations?
I've summarized the specs for these three configurations:
The total number of seats is roughly the same but the distribution is very different - the 7-car sets have a much higher percentage of Business seats. That would make them better suited for runs such as Toronto-Montreal with lots of business travel. Milk-run services serving the smaller cities and towns along the routes would presumably have a higher percentage of Economy class demand and would be better served by the 2x 4-car sets.
The 7-car sets have barely half the power-to-weight ratio of the 2x 4-car short sets, so they would be best used on services with minimal stops, such as Toronto-Montreal. Services with frequent stops are better served by the 2x 4-car sets.
Hopefully there's a solution to the train cycling puzzle that puts the 7-car sets on express services as much as possible, while the 2x 4-car sets get put on local services as much as possible.
The elephant in the room with combining coaches into longer trains is that some departures will need to be cancelled due to the reduction in total trainsets. The trains that remain will also need to make more stops, to maintain service at intermediate stations despite the cancelled trains.

The HEP fleet will presumably remain until shunt enhancer work is completed and the trainsets reformed. At least the Siemens equipment is new and won’t need cycling through heavy refit (other than shunt enhancer install). As for the LRC retirement… who knows when that will be?

Why are we assuming that shunt enhancers are required? Nearly every other railway on the planet manages to detect small trains just fine without shunt enhancers. The issue is specifically with a few models of level crossing gates that CN chose to install. Via's 24-axle trains meet Transport Canada's requirements for electrical conductivity, so TC needs to do their job and tell CN to make the necessary adjustments to their level crossing equipment to detect trains reliably.

Because we don’t have a rail regulator which actually acts like one and sets minimum standards for what host railroads may or may not install and what kind of rolling stock they have to safely detect at what speeds. Red tape comes at a price, but sometimes the lack of red tape comes at an even higher price, at least to the general public…

If it was as simple as saying “yank that gear and put in ones that work better” why haven’t Amtrak and VIA gone to the STB and TC to demand CN and BNSF do so? Presumably that is a worse option, either because they know the railroads will get a decade or more to do so, that the railroads might decide to decrease zone speeds to narrow the gap between passenger and freight, or something else
