You may remember that I wrote about the retirement of the Shibayama Railway (Shibatetsu) 3500 series EMU in March this year. At that time, I mentioned that I would save the replacement for the 3500 series for a future post.
Three months have passed since then, and now I finally have a chance to introduce it.
Please take a look at the photo above—this is Set 3668 of the Shibatetsu 3600 series EMU, which has been newly leased from Keisei Electric Railway. To welcome Set 3668, I recently visited Makuhari-hongo Station on the Keisei Chiba Line and took the above photo, as 3668F occasionally operates through onto Keisei lines.
The technical specifications of Set 3668 are, of course, identical to those of the Keisei 3600 series. However, before entering service with Shibatetsu, the body stripe colors were changed from red and blue (the Keisei colors) to green and red (the Shibatetsu colors).
You may be thinking, “Is this really a newly assigned train? It looks just as old as the former Set 3540.” I understand what you mean. However, as a railway enthusiast, I am quite satisfied with this replacement because: (1) the veteran Set 3668 has escaped retirement, and (2) Set 3668 is a high-performance train.
Set 3668 was originally built in the late 1980s. It currently consists of four motor cars with no trailer cars and is equipped with a VFD traction control system. Japanese railfans affectionately call this trainset “Turbo-kun.” “Turbo” comes from the English word “turbocharger,” while “-kun” is a casual Japanese suffix used for boys or for male friends and colleagues with whom one is on familiar terms. In short, Turbo-kun means “a powerful train.”
Turbo-kun, go for it!
After welcoming Set 3668, I switched gears to another hobby of mine—fossil collecting. As I have mentioned before, fossil collecting has been a lifelong hobby of mine, just like railway enthusiasm. My hunting ground that day was Makuhari Artificial Beach, located near Makuhari-hongo Station. Fossil-bearing rocks dredged from the floor of Tokyo Bay can sometimes be found there.
Please take a look at the photo below—this was my find of the day: Thalassinoides isp. It is not a body fossil but an ichnofossil representing crustacean burrows. It is about 10 cm long and consists of intricately intertwined branches, giving it a somewhat creepy appearance.
That day, I was able to pursue two hobbies during a single trip on the Keisei Chiba Line.
