New book 'Electronics for Model Railways' launched
The book has been written by MERG member, Davy Dick. Asked why he wrote
it, he said:
I believe that there is a need for a book that tries to encompass the
broad electronic facets of our hobby.
It is intended to help new MERG members and those who might be drawn to
There is not a lot of material out there, mainly old texts or books that
solely cover DCC. I think that the contents will be widely welcomed.
I have trialled the book to selected MERG members covering a range of
knowledge and experience, with favourable feedback.

MISTAKES FAULTS and CORRECTIONS
After downloading Part A and Part B of Electronics for Model
Railways, print the following list of corrections and keep
P 151 LEDs are up-side down
P 168 The BC 557 should be BC547 - a base resistor may be
P 8 The 150R limits the current to 60mA
P 8 The green LED should be red and the red LE should be
P 30 The BC557 circuit will not work
P 34 The BC557 should be BC547
P 121 D2 not needed
P 135 Only one 1k resistor should be used and this will prevent
reverse voltage on the LEDs.
P 149 The green LED should be red and the red LE should be green
