For example, down in Melbourne, we obviously different sets of electric trains that are visibly and physically different. At the same time, we have different names for the sets. Comeng Sets, Siemens Sets and X-trapoulos set.
What do you call your differing sets?
Unit Nos. 1-88?
Unit Nos. 201-212 and 221-250 (these look the same as far as I can tell)?
Unit Nos. 261 onwards?
I am sure this would be mentioned somewhere, but I just don't seem to have come across it.
Any help would be great.
As far as I recall,
Unit Nos. 1-88 are called EMU type (for Electric Multiple unit)
Units 60-79 have six traction motors and a cab at one end only. They can run in pairs or with a double ended set.
Other EMUs have eight motors, cabs at each end and can run singly.
Unit Nos. 201-212 and 221-250 are SMU type (for Suburban Multiple Unit}
201 - 212 are made up driving motor, motor, driving trailer using thyristor AC inverters
221 - 250 are made up driving motor, trailer, driving motor using IGBT AC inverters
Unit Nos. 261 onwards are also called SMU type and have the same types of cars as the 221 series.
I think the SMU types are told apart by quoting the number, 201 series, 221 series and 261 series.
There are IMU (Interurban multiple Units) with the same characteristics as the three types of SMU, 101 series, 121 series, 161 series.
The other main type of train is the Inter City type now used on services to Gympie North. (edit)
