Here's an unusual mechanical clock by General Electric. It's made to give the illusion of being a digital clock, even convincing enough with its grid. At first, I thought it had a failed vacuum-fluorescent display, but when I opened it up, it turns out it was a mechanical clock, and the backlight lamp was burned out. After replacing, it now works great!
Interestingly enough, they used standard car lamps as opposed to proprietary bulbs or pre-soldered bulbs, which makes it easier to service it. Might

In this video, we explain the #1 issue with cheap record players such as the Crosley Cruiser: Tinny-sounding audio from the ceramic cartridge that they're equipped with.
Ceramic cartridges are meant to be paired with a high impedance input of at least 1 megaohm, or at least, a velocitizer if using a MAG phono input. Without either method, you get the infamous tinny, thin-sounding audio with non-existent bass. A standard line input is not enough for a ceramic cartridge, and the low impedance acts as a high pass filter, resulting in the bass basically being non-existent. With tube equipment, this wasn't really an issue as the impedance was practically infinite, but with solid-state equipment, this was the main issue.
In most of today's cheap record players, they simply connect the cartridge to a standard line input, but very few of them actually bothers to match the impedance so the cartridge performs at its best.
Schematic at end of the video is, to properly load the ceramic cartridge, and the section for "MAGNETIC" is the schematic for Sonotone's Velocitizer for using a ceramic cartridge on a standard phono preamp. What this does is, convert the amplitude response of a ceramic cartridge into velocity response.
Moving magnet, moving coil, and even moving iron cartridges are constant velocity pickups, while a ceramic cartridge and a crystal cartridge are constant amplitude pickups.

Seeing that the chances of a 2020 holiday train run is likely to be none due to the ongoing COVID-19 pandemic, let's turn the clock back one year when the New York Transit Museum was using the 2018 route for the annual holiday train run (Ran on Sundays from the Sunday after Thanksgiving until the last Sunday of December).
Like the 2018 run, the 2019 route had the holiday train run via the Central Park West line up to 145th St on the "B" platform. Its southern terminal was 2nd avenue, like past runs.

Seen here are two 8-car trains of R32 cars on the J line. This was when many R32s were assigned to the BMT Eastern Division for J and Z service.

We return again with the cartridge comparison with these budget record players!
The Audio-Technica AT3600 is a very popular entry-level moving magnet cartridge, and can be commonly found in many entry-level turntables (and USB turntables) that states that use a moving magnet cartridge. Could also be found on some vintage all-in-one systems from the 1980s-1990s.
The Chuo Denshi MG-09D, also sold as a Pfanstiehl MG-09D, is also very popular entry-level moving magnet cartridge that is also commonly rebadged as the Numark GrooveTool. These can be found in several USB turntables (if not using an AT3600), which includes the Crosley Keepsake. Could also be found on some vintage all-in-one systems from the 1980s-1990s
The Chuo Denshi CZ800, also sold as a Pfanstiehl P-188 or P-190, is a very popular entry-level ceramic cartridge that Skywin uses frequently with their budget turntables, the most popular being their portable turntables, such as the very popular Crosley Cruiser. Some vintage record player restorations also use these cartridges, and so did several vintage all-in-one systems from the 1980s-1990s.
Song is September by Earth, Wind & Fire, from the Greatest Hits Vol 1 LP.
Equipment:
AT3600 - Kenwood P-100 turntable (metal platter)
CZ800 - Victrola ITVS‑200B 6-in-1 turntable (plastic platter)
MG-09D - Crosley Keepsake (plastic platter)
Will be acquiring the GrooveTool version of the MG-09D to use on one of my extra turntables to showcase how a metal platter can improve the sound quality significantly.
Also awaiting a CZ800 with a 1/2 mount, and a vintage amp that has the proper high impedance input for ceramic cartridges (and has tape-out, to record the audio from said amp).
Stay tuned for more in the series!

Note that this is NOT the original compressor on Low-V #5466. According to youtube user electricrailwayman, this, and 2 of the 4 low-v cars at NYCT were rebuilt with WABCO D-3 compressors for the 1979 Diamond Jubilee. BERA has since replaced the D-3 compressor with this model.
Former Westinghouse cars from the mainline Redbird SMEEs were retrofitted with WABCO D-4 compressors after they were rebuilt.
WABCO, now WABTEC, still manufactures this model of compressor to this day.
