At 01:06:50, on the Longfellow bridge to Cambridge (and in many other railroads), what, if any, is the purpose of the two narrow rusted rails positioned between the two main wheel rails? Is they something left over from the old days, like a brake rail? It is not a narrow-gauge issue because the rails are not continuous, but appear only at certain sections. What were those conditions? I have seen these on other systems, but not sure if the did anything. I’m not talking about the London underground, where its the negative return electric rail.

I could be wrong but I believe those use to be the power (third) rail for the long-retired fleet of cars. Though your guess is as good as mines

This is the BEST compilation vlog of all the MBTA lines and stations that I have seen. The images are clear, no talking, good long shot, zoom, and closeups where due. Also , it is nice to capture the station announcements and train arrival signs in the stations. Very good job.

The new Orange Line 1400s and Red Line 1900s need to replace the old 1200s and 1600s ASAP.

To a Degree Yes but with the issues with the new trains.... Keep 01200's on Standby

At Airport Station, what would happen if they forget to lower the pantograph i going inbound? Are there interlock safety switches on the catenary to emergency stop the train before the pantograph get damaged? After all these years somebody must have made the mistake Going outbound, if they forget to raise the pantograph, the trains would simply slide off third rails into dead tracks.

That's good question but I have to guess the process is done automatically without operator interference. As far as going inbound beyond Airport station, the third rail shoe-on from the bogeys are still capable obtaining voltage even without contacting the third rail. So the moment they make contact with the rail they're receiving power

@@MJofLakelandX I think raising and lowering the pantograph are still done manually on this line, because there are driver signs at either end of Airport Station reminding drivers to “Lower Pantograph” and vice versa. One would think this process COULD be automated, but the MBTA is the oldest subway in America. Even with getting new cars, it does not appear that automatic raising and lowering the pantograph was a specified feature. That’s why the possibility of someone passing Airport Station inbound without lowering the pantograph is quite plausible.

@@MJofLakelandX that’s another point I have often wondered about dual-source mixed use train systems like the Blue Lone. The Metro North railroad north of NYC switches between third rail and pantograph at a point near leaving Connecticut, where catenary is used for points north to New Haven, and Amtrak to Boston South Station. Does the drivers action of raising and lowering the pantograph perform a switch of circuitry internally to different current converters, given the difference in voltages and type of current of the third rail versus catenary? I would think that mixing the two different currents would be a disaster, unless the current converter was very smart. I’m inclined to think that lowering the pantograph shunts the converter to third rail mode. But I’m not an electrical engineer so who knows?

Great video! I do suggest setting your white balance a bit differently, but otherwise I love this train movie :D

TBT, I was surprised myself. It did feel like I recorded that much content but I try hitting every interesting station in the system
