PIKO G Scale Rolling Stock Wheel Sizes

Last Updated: 21 May 2022


Wheel Sizes

PIKO uses two different sized wheelsets for their passenger cars and freight cars.

  • 30 mm diameter
  • 35 mm diameter

The 30 mm diameter wheels are sometimes referred to as 29,5 mm. I don’t know the exact size, but recent publications all state 30 mm so I assume that is correct. The 30 mm wheels are slightly smaller than LGB’s wheels, which I believe are 31 mm diameter.


Which size is used for which rolling stock?

35 mm diameter:

  • “Umbauwagen” / “Umbau” Passenger Cars (#37600 & …)
  • “Nahverkerswagen” / “Silberlinge” / “Silver Coin” Passenger Cars (#37620 & …)
  • “TEE” Passenger Cars (#37640 & …)
  • “Reko” Passenger Cars (#37650 & …)
  • German two-axle passenger cars (#37920 & …)
  • German two-axle freight cars (#37900 & …)

30 mm diameter:

  • all other German freight cars
  • all American passenger and freight cars

Since 2015, PIKO also lists the wheel sizes in their G scale catalogue for easy identification.
