Product Description

Seibu Railway 4000 Series (Finished Model)

The Seibu 4000 series was created in 1988 for the purpose of transporting tourists on the Seibu Chichibu Line and Chichibu Railway. The first batch consisted of early cars (4001F-4007F) and later cars (4009F-4015F), and in 1992, four more second batches (4017F-4023F) were added, bringing the total number of trains manufactured to 12.
U-TRAINS produced models of both the unrefurbished and refurbished versions of the first batch of trains (early and late periods) in 2010.
This time, we will be releasing three versions of the product: the unmodified version, the updated version, and the current specification, in addition to the second-generation model as a finished product.
Additionally, as a limited-edition special edition, we will be producing the 4017F train in the E851 electric locomotive livery to commemorate the 55th anniversary of the opening of the Chichibu Line.

[Product Specifications]
Unmodified car: We will produce a model of the car from around 2000, with semi-cross seating extending to the ends of the car, vending machines installed, end stripes, PT4320S diamond-shaped pantographs, and CU72D stainless steel air conditioners, representing the era before the one-man operation modification.
Train set: 4001F
Directional sign: Rapid (Ikebukuro)

The finished product will have the motor installed in the intermediate pantograph car (M1).
The power source is a combination of Katsumi ACE gears and a Canon EN22 motor.
The wheels will be the corrugated gray type.
The headlights, taillights, front destination display, and side destination display will illuminate.
The circuit board is manufactured by U-TRAINS and uses a circuit designed to reduce lighting flicker during operation.
The FS372 dedicated bogie uses an original product in which the obstacle deflector of the leading bogie is molded as a single unit.
The lead car will be equipped with a dummy electrical connector type coupler, and will be manufactured with the ability to replace it with a Katsumi custom coupler when connecting two lead cars together.
