## Locomotive numbering system of the Swiss railways |

These numbers look like German, Spanish, Czechian numbers: 000 000-0, the first group of three denotes the class, the next group of three is the serial number, and the last digit is the check digit, to check whether the number is correct.

The numbers can be extended to international numbers later, by adding a sequence such as 90 85 0 at the left.

A number of Swiss railways (mostly standard gauge, narrow gauge only SBB CFF FFS so far) have started to write new numbers on new or rebuilt locomotives and railcars. Old units are not yet renumbered, so there will still be several years until the new system is fully implemented, and both systems will coexist for some time.

- 0: Museum locomotives, steam locomotives
- 1: Narrow gauge vehicles
- 2: Tractors (small shunting locomotives under 500 kW)
- 3: Electric locomotives with less than 4 powered axles
- 4: Electric locomotives with 4 powered axles
- 5: Railcars (EMUs, DMUs)
- 6: Electric locomotives with more than 4 powered axles
- 7: not yet in use
- 8: Diesel locomotives
- 9: Electric shunting locomotives

*if 1st digit = 0:*0 = steam, 1 = electric, 2 = railcar, 3 = Diesel, 7 = tractor, 8 = snowplough, 9 = special purpose*if 1st digit = 1:*0--2 = locomotives, 7 = tractor, 8 = snowplough*if 1st digit = 2:*0 = battery, 1 = electric, 2 = electric and Diesel, 4 = Diesel, 5 = electric and battery*if 1st digit = 3--4 or 6:*denotes locomotive generation*if 1st digit = 5:*0 = long distance EMUs, 1 = short distance EMUs, 4--7: single power cars*if 1st digit = 8--9:*number of powered axles

- 0--4 = owner SBB CFF FFS, for electric locomotives and railcars: 0 and 1 =
1 current system, 2 = 2 c.s., 3 = 3 c.s., 4 = 4 c.s.

For tractors (1st digit = 2): 0 = 0--99 kW, 1 = 100--199 kW, 2 = 200--299 kW, 3 = 300--399 kW, 4 = 400--499 kW - 5 = owner BLS (was BLS/BN/GBS/SEZ)
- 6--8 = owner various private railways, see 4th digit
- 9 not yet in use

*if 3rd digit = 1--5:*part of serial number*if 3rd digit = 6:*0 = SOB (was BT), 1--3 = RM, (4 = was old SOB), 5 = SZU, 6 = MThB, 7--8 = THURBO, 9 = BABHE (was OKK)*if 3rd digit = 7:*0--1 = TPF (was GFM), 2 = OeBB, 3 = TRN (was RVT), 4 = CJ, 5 = TMR (was MO/MC), 6 = OC, 7--9 = various private railways incl. Lokoop*if 3rd digit = 8:*0 = PTT, (1 = was STB), 2 = TSOL, 3 = TRAVYS (was PBr), 4 = BDWM (was WM), 5 = ST, 6 = RB (was ARB/VRB), 7 = RHB, 8 = LO, 9 = KLB
