I followed that link to the Rockyview website - looks like nobody is keeping up their webpage. Elbow Valley has been out of 33 for ages. They're just south of the last set of lights on Hwy 8 now. They have an engine and a tender. There was never a tender in 33 from Rockyview.
All the stations that had numbers in the 50-99 block were moved out to higher numbers.
This is a summary from the email my chief at Redwood sent us officers:
Redwood - 120
Cochrane - 151, 152
Rockyview - as follows:
Elbow Valley - 101
Springbank - 102
Madden - 105
Balzac - 107
Irricana - 108
Langdon - 111
Crossfield - 154
Beiseker - 130
Chestermere - 116
Bighorn - as follows:
Ghost River (Benchlands) - 167
Jamieson Road - 168
Exshaw - 169
A lot of these have some other numbers reserved for future use. Example - Rockyview's reserved numbers for, for example, the long-rumored Bearspaw station, should be obvious.
